On Windows 10 or 8.1, hold down the “Shift” key on your keyboard and click the “Restart” option in the Start menu or Start screen. If your computer isn’t booting properly, Windows will automatically boot to this menu after a failed boot. If it doesn’t, then even the startup options themselves are corrupted.
Your computer will boot to the special recovery menu. Click the “Troubleshoot” tile, click “Advanced Options,” and then click “System Image Recovery.”
Choose your keyboard layout when asked, and then select the “Restore your computer using a system image that you created earlier” option in the System Recovery Options window. Select a system image from a connected drive and go through the rest of the wizard to restore it.
How to Restore Your Backup with a Recovery Drive
Insert the recovery drive and boot from it. This may require changing the boot order in your computer’s BIOS or accessing a “boot devices” menu.
On Windows 10 or 8.1, you’ll see the same options you would in the boot options above. Just select Advanced Options > System Image Recovery. On Windows 7, select the “System Image Recovery” link.
How to Restore Your Backup from Windows Installation Media
Boot from the Windows installation media like you would the recovery drive above. Just as if you were booting from a recovery drive, this may require changing the boot order in your computer’s BIOS or accessing a “boot devices” menu.
Whatever type of installation disc you’re using, go through the first few screens until you reach a screen with an “Install now” button. Ignore that button and click the “Repair your computer” link at the bottom-left corner of the window to access the same system repair tools you’d access from a recovery drive or from the boot-up menu above.
