What can I do if my Windows 8 computer won’t boot from the USB recovery media or boots from it and gives an error regarding UEFI?
To boot from the USB recovery media, your computer’s UEFI Boot Mode should be set to "UEFI."
A small number of users might encounter the following problem: When the UEFI Boot Mode is set to "UEFI," the recovery media won't load. When it's set "CSM," you see an error saying “BIOS is not UEFI.”

USB recovery media ordered from Toshiba currently should not have this problem. However, a small number of USB recovery media shipped in the past may see this error. If you do, please contact customer support and request replacement USB recovery media.

You can use a second USB flash memory drive to correct this. Please note that this will format the new USB stick. You’ll lose all data stored on it. Follow the directions carefully; using the wrong disk number (as described in step 5) could cause you to lose all data on the wrong drive.
