Installing Windows from flash drives very convenient. Keeping Windows on a flash drive is much more secure than on a disk. Install from flash drives will also be faster than from disk. There are cases when the computer does not work or simply does not have an optical drive (DVD / CD) ROM. Then setting with flash drives- this is a very good way out of the situation. If you need to reinstall Windows on a laptop, somewhere on the road, it will be more convenient to do this with flash drives.

You will need

• Computer, Windows OS, flash drive, UltraISO program, DAEMON Tools program, Internet access

Instruction

First of all, you need to write Windows to a flash drive. The capacity must be at least 4 gigabytes. Download the version of Windows you need from . The operating system downloaded from the Internet is in ISO format (virtual disk). Next, download the UltraISO program. It will be required in order to make it bootable.

Open the Windows image using the UltraISO program. Go to the "Boot" menu and select "Burn Disc Image". Creating a bootable flash drives will destroy all information stored on it. Learn it. Insert your flash drive into your computer. The flash drive will appear in the program menu, select it. Select "USB-HDD" as the recording type and click "Burn". The recording process will last from 10 to 25 minutes. Upon completion, you will be informed that the process has been successfully completed.

Restart your computer and continuously press the "DEL" key. This will take you to the BIOS. Select the line "BOOT", then in the line "BOOT DEVISE PRORITY" select "USB-HDD". Click on the "Save end Exit" command.

Computer and the process of installing Windows from a flash drive begins. If you do not want to install Windows at this very moment, just remove the USB flash drive. In order to start the installation process, you just need to insert the USB flash drive into the USB port before turning it on.

If you don't want to download Windows from the Internet and it's already on the disc, you need to convert it to ISO format. Download and install DAEMON Tools. Insert the disc with DAEMON Tools into your computer's drive. In DAEMON Tools select "File" menu, choose "Create New Image". After the process is complete, you will have Windows in an ISO that you can burn and install Windows from it as described above.

Newer versions of Windows operating systems include a backup or image feature. It allows you to quickly bring the system to a working state without resorting to a complete reinstallation.

You will need

• - DVD.

Instruction

To create an image of the Windows Seven operating system, go to the "Control Panel" menu. Now open the "System and Security" menu and go to the "Backup and Restore" submenu.

Find the item "Create a system image" and click on it. Wait while the operating system prepares the files for archiving. Specify the location where the future OS image should be stored. To increase the degree of data security, it is recommended to use external USB drives. This will restore the operating state of the system even in the event of damage to the hard drive used.

Click the "Next" button after selecting the device to store the image. A window will open with a list of sections that will be included in the archive. Usually these are the system and boot partitions of the hard drive. Click the "Archive" button. This process takes quite a lot of time. It is better to leave the computer on at night.

Unfortunately, it is not enough just to create an image. After all, it will need to be launched in the event of a system failure. Repeat the procedure for entering the "Backup and Restore" menu. Click the "Create System Recovery Disc" button.

Insert a blank DVD into a working drive. Click the "Create Disc" button. Wait until the required files are written. Please note that you can use a regular Windows Seven installation disk as a recovery disk.

If the operating system stops loading, insert the created disk into the drive. Turn on the computer and press the F8 key. Select your DVD drive from the menu that appears. After a menu appears containing options for restoring the operating system, select Restore the system from an image.

Now specify the storage location for the archived copy of Windows. Wait until the process of restoring Windows Seven OS from the image is completed.

You can start the installation of the operating system in several ways. Inexperienced users often start it from the desktop. This often leads to the fact that the old OS is not removed, but the new one is simply installed on top of the old one. As a result, the user gets two operating systems installed on the same hard disk partition. Much more correct is to start loading the OS from the BIOS.

You will need

• - a computer;
• - Windows boot disk.

Instruction

Turn on your computer. Immediately after that, press the Del button on the keyboard. Instead of turning on the computer normally, you will find yourself in the BIOS menu. If you use , there may be other options instead of the Del key. You can find this information in the manual or on the official website of the manufacturer.

In the BIOS, using the arrows on the keyboard ( will ), select the Boot Device section, and in it - the number 1. Press Enter. From the list of suggested devices, install the CD-ROM. Next, in the main BIOS menu, select Exit and press Enter. After that, a dialog box will appear asking you to save the settings. In this window, select Save and Exit. The computer will restart.

Insert the operating system disc into your computer's optical drive. It must be bootable, otherwise its download will simply not start. If the disk autoload window appears, close it. Restart your computer. Now, when you turn it on, the operating system will automatically boot. But a situation may arise when the message Press any key appears on the screen. In this case, to activate the boot disk, you need to press any button on . Wait for the first dialog box to appear. Install the operating system on the computer according to the prompts of the "Wizard".

Next, you need to return the settings back, since the presence of any disk in the drive will slow down when turned on. After the operating system is installed, go back to the BIOS menu, but this time in the Boot Device section, set your hard drive as the first boot source for the computer (number 1). When you exit the BIOS, also save the settings. The computer will restart. Now it will turn on normally.

USB devices, including storage media, are actively developing and have many modifications. Sometimes these devices do not work or work with errors. Many users are ready to say that they bought defective products, but the reason may not be marriage at all, but incorrect BIOS settings.

You will need

• Computer, USB device

Instruction

To open the BIOS, press Del after turning on the computer and before the operating system starts loading. You may need to press a different key to enter the BIOS on your computer. In the lower left corner when checking the RAM, there is an inscription Press Del to enter setup. If another key is written instead of Del, press it.

The BIOS window opens. You need to control the BIOS with the arrows and the Enter and Esc keys. Main parameters for equipment: Disabled - disable, Enabled - use. Depending on the manufacturer and model, the versions and directory names in the BIOS may differ. The following are the most common names.

The Advanced (Advanced BIOS features) menu disables or uses the USB controller under the USB Functions (USB Controller/USB Ports/USB Device/ Integrated (OnChip) USB Controller) command. The Enabled/Disabled command - enables/disables all USB ports, Both - makes all ports available, Primary - only ports on the rear panel are available. 2/4/6/8 USB Ports - the number of ports available for operation.

Modern PCs are very productive, they are able to process hundreds of tasks per second. If you connect a third-party device to it, then the performance will increase significantly. It can be a scanner or a printer, a smartphone or a webcam. All this makes the computer a unique tool.

Non-working USB ports are needed by the user so that strangers cannot steal important information from the PC. This is a kind of privacy policy. A person will not be able to connect a USB flash drive or hard drive with a USB connector in order to copy important data. But it is important to make sure that the connectors for the keyboard and mouse remain working. One of the simplest solutions is to disable USB ports through the registry on Windows 10. The main advantage of this method is that you do not need to download different software, thereby cluttering up your PC

So let's get started. Press the key combination Win + R. On the command line, write regedit and press Enter.

We have a registry. In its left part we find the *HKEY_LOCAL_MACHINE* section and double-click on it. There is a folder *SYSTEM* in which the subsection *CurrentControlSe* is hidden. Next, we find * Services * and look for * USBSTOR * in it. In the right part of the registry, find the *Start* value and click on it. You will see the *Change DWORD Value* window. To disable ports, select 4 instead of 3 in the *Values* field.

3 - enable USB ports, 4 - disable. Now we reboot the PC and find that the USB ports are disabled.

Everything is very simple here. Right-click on *My Computer* and select properties.

In the window that opens, select the section *Device Manager*.

Before us is a tree of all devices of our PC. Find and select *USB controllers*. We chose this section and through RMB we disable all the necessary ports.

It should be noted that this method does not always work. There were times when 2 out of 4 ports or one turned off.

Using Third Party Programs

You can set a ban on USB ports in the simplest way - through programs. One of these is USB Ports Disabler. This is a free program that disables all ports on your PC. The utility has a very simple and minimalistic interface. The program is free. USB Ports Disabler detects and disables the USBSTOR we saw in the registry. So, reading data from a USB drive will be impossible.

Download USB Ports Disabler- http://www.softportal.com/software-42029-usb-ports-disabler.html

Another utility worthy of attention. First of all, USB Manager is compatible with all version of Windows. The program itself is lightweight, and the installation will not raise questions. The utility is fully multilingual, there will be no difficulties with the language. USB Manager disables/enables all USB ports on your PC in one click.

It is worth remembering that the main malicious files enter the system through USB drives, so by disabling the read ports, you thereby protect yourself from a headache. You can select a specific port that you would like to disable, which could be a printer or scanner port. The program itself works quickly, clearly and correctly. The software is updated very often, by the way, in the latest version, the shutdown system for the user has been updated.

Immediately after installing the Windows 7 operating system, some users notice that USB ports do not work on their computer. Let's see what actions need to be taken in order to be able to connect devices to a PC using the above protocol.

We note right away that this article will talk about a specific problem after installing, reinstalling or updating Windows 7, that is, about a situation where everything worked fine before installing the operating system, and after following these procedures, it stopped functioning. We will not dwell on other possible malfunctions related to the fact that the computer does not see USB devices. A separate lesson is devoted to this problem on the site.

The problem we are studying has two main causes:

• Lack of necessary drivers;
• Incorrect entries in the system registry (after updating Vista to Windows 7).

Method 1: USB Oblivion

This solution is just right if you upgraded to Windows 7 from an earlier operating system. This may leave entries in the system registry about previous connections of USB devices, which will be incorrect in the updated OS, which will lead to problems with further connection attempts. In this case, all records of previous connections must be deleted. The easiest way to do this is with the USB Oblivion utility, which is just designed for this purpose.

Method 2: Microsoft USB Troubleshooter

Microsoft has its own USB troubleshooter. Unlike the previous utility, it can help not only after installing the operating system, but also in many other cases.

Method 3: Driver Pack Solution

After installing Windows 7, your computer may not be able to receive and transfer data via USB due to the lack of necessary drivers. This situation is especially common if USB 3.0 connectors are installed on a stationary PC or laptop. The fact is that Windows 7 was developed even before the specified standard began to be massively implemented. For this reason, the basic version of the named OS immediately after installation lacks the necessary drivers. In this case, they need to be installed.

The easiest way to solve this problem is if you have a disk with the necessary drivers. In this case, you just need to insert it into the drive and extract the contents to your computer using the displayed prompts. USB ports will be restored. But what to do if the necessary disk is not at hand? The actions to be taken in this situation are discussed below.

The easiest way to solve the task is with the help of, designed to find and install the missing drivers on the computer. One of the best applications in this class is .

1. Run the program. When activated, it will simultaneously scan the system for connected devices and detect missing drivers.



2. Click on the button "Set up your computer automatically".



3. After that, the program itself will create a restore point in case an error is made during the setup process or you just want to roll back to the old settings in the future.



4. After that, the procedure for installing drivers and configuring some PC settings will be performed.



5. After the procedure is completed, a message will appear that all the necessary settings have been completed and the missing drivers have been installed.



6. Now you need to restart your PC. click "Start". Next, click on the triangular icon located on the right side of the button "To finish work". Click .



7. After restarting, you can check if the USB ports are working or not.

Method 4: Manual driver installation

The required drivers can also be installed without installing additional software to search for them. But for this you have to tinker a little more.

1. Click "Start". Sign in "Control Panel".



2. Go to "System and safety".



3. In the list of tools "System" click on item "Device Manager".



4. Interface will be displayed "Device Manager". The shell that opens will list the different types of devices that are currently connected to your desktop or laptop. Click on the name of the group "USB controllers".



5. A list of items will open. You need to find one of the following names in the list:
   • Generic USB Hub;
   • Root USB Hub;
   • USB Root Controller.

   These are the types of ports. The list will most likely include one of these names, but it may appear multiple times, depending on the number of USB outputs on your computer. Despite this, it is enough to do the procedure described below with one of the identical elements, since the drivers on the computer will be installed for all ports of the same type. If there are several different names of elements from the above list, then for each of them you will have to perform manipulations separately.

   So right click ( PKM) by element name and select from the list "Properties".



6. A window will open in which you need to click on the name of the tab "Intelligence".



7. After that in the field "Properties" select an option from the drop-down list "Hardware ID". In area "Meaning" the device ID will be displayed, that is, in our case, the USB port.



8. This data must be saved. They can be recorded or copied. For the second option, just click PKM by area content "Meaning" and select from the menu "Copy".

   

   Attention! The main thing is that after that, do not copy any more data until the operation to search for the necessary drivers is completed. Otherwise, you'll just replace the information in "Clipboard" about driver IDs with new data. If you still need to copy something else during the procedure, then first paste the data from the equipment properties window into "Notebook" or any other text editor. Thus, if necessary, you can quickly copy them again.

9. Now you can proceed directly to the search for the necessary drivers. Open a browser and go to one of the popular ones - DevID or DevID DriverPack. You need to drive into the search field of the site the data that you copied in advance, and click on the button that starts the search.



10. After that, the results of the issuance will open. Select the option that matches your operating system (in our case, Windows 7) and its bitness (32 or 64 bits), and then click on it.

    

    If you are using the DevID DriverPack service, then you will need to specify the OS name and bit depth there before starting the search.



11. After you have gone to the driver page, download it, unpack it from the archive if necessary and run it on your computer, following the prompts that will be displayed on the monitor. After restarting the PC, the problematic USB ports should work. If this did not happen, then look for the origins of the problem in incorrect registry entries, as described above.



There is another option for downloading the necessary drivers - do it from the official website of the manufacturer of the USB controllers that are installed on your PC. But in this case, you must definitely find out the address of this Internet resource, as well as the exact name of the controller model.

There are two main reasons why USB ports may not work after installing Windows 7, although before that they functioned normally. Firstly, these are incorrect entries in the system registry left over from the old OS, and secondly, the lack of necessary drivers. Each of these problems is solved in several ways, which we have described in detail in this article. So users, having familiarized themselves with the material, can independently choose the most convenient and acceptable course of action for them.

There are different types of problems associated with the operation of the front USB ports on a personal computer. Sometimes there is a problem when all the front ports are not functioning. In other cases, when only one does not work or works poorly. We will try to tell you about each of the situations when usb ports do not work.

Simultaneous failure of all front ports

To begin with, it is necessary to clarify that the front ports differ from the rear ones in that they are connected to the "motherboard" through a special cable, while the latter are part of the motherboard.

The first likely reason why the USB ports on the front of the computer often do not work is that the USB port controller is disabled. It is located on the motherboard. You can enable it using the BIOS menu. You can get here by restarting your computer and pressing one of the keys. This is usually the F2 or Delete key.

In the BIOS, you will need to go to the Integrated Peripherals section. There is a USB Configuration menu here. You need to find out what position the USBController is in. If the opposite is Disabled, then the controller is not working. Switch to the Enabled position. Save the changes and restart the computer.

You can check all USB ports by going to Device Manager. It contains the "USB Serial Bus Controllers" section. Some of the items may be marked with a yellow exclamation mark. Why? This indicates a malfunction or poor performance of one of the ports. Detailed information can be found in the context menu called by right-clicking on the device name. It is worth deleting all controllers in the "Dispatcher", and then restarting the computer. Windows is capable of restoring all controllers at boot time on its own.

The Windows operating system sometimes disables one or all of the front ports specifically to save power. We can manage the power ourselves, so our task at this stage is to prohibit the system from doing this. We again need the "Device Manager" and the "Universal USB Bus Controller". Next, click on the line "USB Root Hub" with the left button. Here we go to the "Power Management" menu. Remove the checkmark from the "Allow shutdown to save power" checkbox. We do this procedure with each USB.

There is another reason why they do not work, lies in the failures or malfunctions of the Windows system. Most often this happens if constant updates are disabled on the operating system. It is highly advisable to restore lost system files or reinstall Windows completely. Problems with the front ports arise due to incorrect assembly of the OS. Therefore, it is important to use only verified Windows builds.

What to do if only one front USB input is not working

One possible reason why this happens is that there is a problem with the ribbon cable connecting the front ports to the motherboard. Then the problem with the operation of one of the ports is solved by replacing this cable on your own or with the help of specialists.

A malfunction can occur if we connect several devices to the front USB ports, for example, an external drive and a phone at once, or something else. Electricity may not be enough for one of them. This situation leads to both shutdown of the port and its intermittent operation. This is due to the fact that the front port interface may not have an additional power source, that is, an adapter. Sometimes we don't notice that the front USB ports are bad. Problems arise only when the main adapter is not enough for our immediate needs. And they are solved by purchasing a USB hub with an additional power source. After the replacement, we get the opportunity to connect any peripheral devices.

Before you start any of the corrective actions listed in the article, you need to check the contacts for connecting the cable to the motherboard. A lot of problems with the front USB ports can be solved in this way.

The reasons for the problems due to which USB ports on a laptop do not work can be completely different - from hardware failure to “flying” motherboard drivers or the controllers themselves.

However, usually the user can deal with most problems on his own, without contacting specialists - if he knows how to do it.

If there are a lot of USB ports on a laptop (for example, 3 or 4), the problem may not be so critical, and its solution can be postponed.

But if there are only 2 connectors or the constant need to use connected devices - flash drives, and even printers - the issue should be resolved as soon as possible.

Moreover, some methods will take no more than a few minutes.

First Troubleshooting Steps

The message that appears on the screen about the termination of the USB ports or the lack of reaction from the laptop to the drive installed in the appropriate slot may indicate.

Sometimes you can solve them with a normal reboot - there is a small chance that the fix will happen automatically.

Increase the likelihood of a positive reboot effect, which really helps sometimes, You can do it in an unusual way:

1 Completely disconnect the laptop from the mains (if it was, for example, charging);

2 Remove the battery and leave the laptop in this state for about 5 minutes;

3 Insert the battery back and turn on the device.

If no messages about idle ports appear on the screen, but the flash drive is still not readable or a peripheral device is not connected to the laptop, it is possible that the problem lies precisely in this equipment.

The assumption is tested by connecting gadgets to other ports of the laptop - or another computer.

Other USB devices

Another problematic situation with USB ports occurs when a large number of external devices are connected to the laptop at the same time.

For example, the user has already connected three gadgets to four ports ( , and ), after which he tries to install a flash drive as well.

Sometimes such a drive simply will not be detected by the system - and turning off 1-2 peripheral devices allows you to check the assumption.

Simultaneous connection to a laptop of a large number of USB devices and adapters.

Most often, this situation does not occur when peripherals are connected directly to the laptop, but when using a “hub” (a USB hub that increases the number of connections).

You can solve the problem by reducing the number of connected devices - or even better, by removing the hub and connecting all gadgets directly.

Incorrect BIOS configuration

In the list of ways to solve the problem with USB ports, you can find.

Sometimes, using this interface, it turns out to enable controllers that turn off on their own on the system board.

Activation requires several steps:

• Reboot the system while simultaneously pressing the function keys to enter the BIOS (for some laptops it's F1 or F2, for others it's Del or Esc).
• Select the Advanced or Integrated Peripherals section.
• Go to the USB Configuration menu item and change the value of the parameter in the USB Controller section (there may be several and with different names) to Enabled.

BIOS interface settings.

After rebooting, the hardware configuration on the laptop will change, and USB ports that were not recognized by the system before that may turn out to be working.

System settings

A battery-powered laptop may automatically turn off some controllers to save power - especially if it approaches critical values.

In this situation, first of all, you should connect the laptop to the network, and then change the power settings, by doing the following steps:

1 Open Device Manager.

2 Select the branch denoting serial bus controllers.

3 Find and open the USB Root Hub subkey.

4 Open the properties of the hub by double-clicking and go to the power settings.

If the problem was incorrect power consumption settings that caused the laptop to automatically turn off ports, a checkmark will be checked here to allow turning off the power of the hub.

By removing it, you can restore the functionality of the ports.

The steps are repeated for each hub if there are several on the laptop.

Prevent the system from turning off USB ports to save power.

Problem with drivers

The problem may be - and in most cases it is - in problems with USB drivers.

You can find the problem by going back to Device manager(via computer properties or by typing devmgmt.msc in mmc).

It is possible that one of the ports is marked in the list with a special icon - a yellow triangle with an exclamation mark, indicating a malfunction of the equipment.

The problem can be tried solve in one of 2 ways:

• Try updating the drivers (preferably an Internet connection) in the properties of the USB controller.
• Remove the device marked with a yellow triangle from Dispatcher and restart laptop.

When using the second option, the rebooted system will try to install new software for detected "new" hardware. Sometimes the operation of the port is restored.

For the first option, you may need to find out the ID number by which the Web searches for the corresponding driver - this identifier is located in the device properties on the details tab.

Determine the USB port ID.

The problem, which is the incorrect operation of the motherboard drivers (usually occurs with outdated laptops released several years ago), is solved by downloading and installing the appropriate software.

To do this, the laptop user must first find out - for example, use the AIDA64 application, which is paid, but also works without entering a key confirming payment for a certain trial period.

The name of the device will help identify and msinfo32 command, entered in the "Run" form (called by the keys Win + R).

Determine the name of the motherboard.

You can try to find drivers for the corresponding board on the website of its manufacturer - or on the resource of the company that developed the chipset.

You should know: In the absence of time and experience in finding and updating drivers, you can use the help of the DriverPack Solution utility. After installation on a laptop, it will independently check and update all the necessary software. The disadvantage of using this method is that if you do not choose to manually configure updates, the application will automatically replace the drivers for almost every detail and even update some programs - this usually takes several hours.

Utility for searching and updating control programs and other applications.

Incorrect operation of the operating system

Replacing this part returns the port (or several connectors at once) to its normal state.

In order to encounter such problems as rarely as possible, the user should not connect a large number of USB devices to the laptop - especially using special splitters ("hubs").

It is also worth enabling automatic installation of updates in the corresponding section of Windows - this usually allows the system to solve problems with drivers on its own.
