A bootable recovery USB drive can help you repair or restore your PC, in case problems occurs. You can create a recovery DVD, but as they are less used we decided that a USB flash drive is easier to find.
Here’s how to create a Windows 8 USB recovery drive
1. From the Windows 8 Start screen, type “recovery”, then under the Search box choose Settings (to see only Settings related results), from the results list choose Create a recovery drive.
2. When the Recovery tool appears, check the box “Copy the recovery partition from the PC to the recovery drive” if you want the recovery tools that came with your PC to be included in the recovery drive. If the checkbox is gray and inactive, that means your PC doesn’t have a recovery partition. Click Next.
If you want to copy the recovery partition, you’ll need at least 16GB of space on the USB flash drive. If you will create the recovery drive without copying the recovery partition you’ll need only 300MB
3. Make sure that the USB flash drive is empty, the data left inside will be deleted. When you get to the end of the Wizard, click Create button and wait till the drive creates.
That’s all. Now you can boot the Windows 8 with your recovery drive and perform a refresh, reset, system restore, automatic repair.
