Windows 8 has the ability to create a bootable USB flash recovery drive that can be used to troubleshoot a Windows 8 computer that is unable to start. A recovery drive is the same as a startup repair disk, but instead of being on a CD/DVD it is on a bootable USB drive. Once you boot up a Windows 8 computer with a Recovery Drive you will have access to a variety of diagnostic and troubleshooting utilities that can help resolve issues you may be having.
It should be noted that a recovery drive is not the same as a Windows 8 DVD and you cannot use it to install Windows 8. It is also important to create the recovery USB drive on the machine with the same bit-type as the one you need to repair. If you create the drive on a 32-bit machine you will only be able to repair 32-bit versions of Windows 8. The same goes for 64-bit versions of the recovery drive. Last, but not least, Windows 8 will format the USB flash drive that you use to create the recovery drive. Therefore, make sure you backup all your data before beginning this process.
To create the Recovery Drive, type Recovery Drive at the Windows 8 Start Screen. When the search results appear, click on the Settings category and then click on the Create a recovery drive option. This will display a User Account Control prompt, which you should click on Yes to continue. This will open the Recovery Drive program.
Make sure you have a USB flash drive that is at least 256MB inserted into the computer and then click on the Next button. You will now be presented with a screen where you will prompted to select the USB flash drive that you would like to use for the recovery drive.
Select the USB flash drive that you wish to use and then click on the Next button. You will now be shown a warning stating that your USB flash drive will be erased.
If you are ready, click on the Create button and Windows will turn your USB flash drive into a bootable recovery drive.
When it done you will be shown a screen that states that the recovery drive has been created.
You can now remove the flash drive and store it in a safe place.
In the future if you need to use the recovery drive to start Windows, you can insert it into a Windows 8 machine and boot off of it. If you are unable to to boot off the USB drive then you will need to go into your BIOS and enable it as the first boot device. Once your computer starts booting up off the USB Recovery Drive, you will be presented with a screen asking what keyboard layout you would like to use.
Select the keyboard layout you wish to use by left-clicking on it once. You will now be at a screen where you can choose an option to perform.
