Windows 8: Modify UEFI Boot Order in BIOS
This section provides a tutorial example on how to modify UEFI boot order in BIOS in order to boot from Windows 8 repair disc directly.
If your Windows 8 computer is using the Unified Extensible Firmware Interface (UEFI) for booting, you need to play with the BIOS setup to boot directly from CD or other devices. This tutorial shows steps to modify boot order on a Dell Inspiron computer.
1. Press and hold down "F1" key when you restart your computer. You will see the BIOS setup screen.
2. Use the right arrow key to select the "Boot" menu. You will see the default boot option is UEFI.
3. Use the down arrow key to change "Secure Boot" to "Disabled". Then change "Boot List Option" to "Legacy". You will see the boot order changed to:
Legacy Boot: Network Hard Drive Removable Drive USB Storage Device CD/DVD/CD-RW Drive UEFI Boot: Windows Boot Manager Network Boot
4. Move "CD/DVD/CD-RW Drive" to the top of the list. Then save the change and exit.
Now your computer should be able to boot from the Windows 8 Repair Disc directly now. But remember to change it back to the default to use the secure boot option.
The picture below shows you the boot order with legacy and UEFI boot options mixed together:
