System recovery options can help you repair Windows if a serious error occurs.

In the left pane, click Create a system repair disc, and then follow the steps. If you’re prompted for an administrator password or confirmation, type the password or provide confirmation.

Note: If you’re prompted to insert a Windows installation disc, it means that the files needed to create the system repair disc can’t be found on your computer. Insert a Windows 7 installation disc.

Insert the system repair disc into your CD or DVD drive.

Restart your computer using the computer’s power button.

If prompted, press any key to start the computer from the system repair disc.

If your computer isn’t configured to start from a CD or DVD, check the information that came with your computer. You might need to change your computer’s BIOS settings.

Choose your language settings, and then click Next.

Select a recovery option, and then click Next.

Tip: Print these instructions and keep them in a safe location with your system repair disc.

Start your computer from a Windows 7 installation disc or USB flash drive

You might need to start, or boot, your computer using the Windows 7 installation disc or a USB flash drive if you want to:

Install or reinstall Windows 7.

Recover Windows 7 from a serious error. If your computer won’t start Windows at all, you can access Startup Repair and other tools in the System Recovery Options menu from the Windows 7 installation disc or USB flash drive. These tools can help you get Windows 7 running again.

Note: If you use a Tablet PC or other computer with a touchscreen, you might need to attach a keyboard and mouse in order to use Startup Repair and other tools in the System Recovery Options menu.

Turn on your computer, insert the Windows 7 installation disc or USB flash drive, and then turn off your computer.

Restart your computer.

Press any key when prompted to do so, and then follow any instructions that appear.

When the Install Windows page appears, click Install now to begin the installation process or click Repair your computer to access system recovery options.

Follow the instructions.

If the Install Windows page doesn’t appear, and you aren’t asked to press any key, you might have to specify that your computer uses its DVD drive or a USB flash drive as the first startup device. To do this, you need to change settings in the computer’s basic input/output system (BIOS).

Note: Most newer computers can start from a USB device, but some older computers might not have this capability. For more information, check the documentation that came with your computer or go to the manufacturer’s website.

Before you change BIOS settings, check the information that came with your computer or go to the computer manufacturer’s website. Specific procedures for accessing the BIOS and changing settings can differ depending on your computer’s manufacturer, or you might be able to choose which startup device your computer uses without changing BIOS settings.

Warning: Be careful when changing BIOS settings. The BIOS interface is designed for advanced users, and it’s possible to change a setting that could prevent your computer from starting correctly.

Turn on your computer, insert the Windows 7 installation disc or USB flash drive, and then restart your computer.

Newer computers often display a startup (or boot) menu. On the startup menu, choose «BIOS setup,» or «BIOS settings,» or something similar.

Procedures vary depending on the BIOS manufacturer. Usually, you must press a key (such as F2, F12, Delete, Esc) or a key combination immediately after you turn on your computer but before Windows starts. If the Windows logo appears, you need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer again.

The BIOS setup screen appears. On the BIOS setup screen, choose the option called «Boot order,» or something similar. Boot order settings might also be listed under «Advanced settings» or something similar.

Select your DVD drive or USB flash drive as the first startup device. (The USB flash drive might be listed under «Removable devices» or something similar.)

Save the setting changes, and then exit the BIOS.

Restart your computer, and then start Windows 7 from the installation disc or USB flash drive as previously described.

Create a recovery drive

It’s a good idea to create a recovery drive. That way, if your PC ever experiences a major issue such as hardware failure, you’ll be able to use the recovery drive to reinstall Windows 10. Windows updates to improve security and PC performance periodically so it is recommended to recreate the recovery drive annually. Personal files and any applications that did not come with your PC will not be backed up. You’ll need a USB drive that’s at least 16 gigabytes.

Warning: Use an empty USB drive because this process will erase any data that’s already stored on the drive.

To create a recovery drive in Windows 10:

In the search box next to the Start button, search for Create a recovery drive and then select it. You might be asked to enter an admin password or confirm your choice.

When the tool opens, make sure Back up system files to the recovery drive is selected and then select Next.

Connect a USB drive to your PC, select it, and then select Next.

Select Create. Many files need to be copied to the recovery drive, so this might take a while.

If you ever need to use the recovery drive to reinstall Windows 10 on your PC, see Recovery options in Windows 10 for further instructions. It’s a good idea to back up your files frequently because the recovery drive isn’t a system image. It doesn’t contain your personal files, settings, or programs.
