I'm trying to install Windows 8.1 using a USB stick from UEFI mode. I used Rufus to format the USB stick as "GPT for UEFI".
The problem is that my PC can boot in UEFI mode only if I turn Secure Boot off. Secure boot in the BIOS is enabled and grayed out. Is there a way to boot from the USB stick in UEFI mode when Secure Boot is enabled? Alternately, is there a way to disable secure boot?
