Hello, I'm trying to disable UEFI on my computer. I did this on some other PC's and it all worked out fine, but I got stuck with this one. The BIOS does have a "secure boot", "fast boot", and "quiet boot" option, but even when I disabled them all I could still only boot into windows 8 (I'm using a USB-stick which worked fine on another computer). I can't find a CSM or Legacy boot option anywhere! Also, when I select my boot order, it says "UEFI:" in front of my USB. Pictures: Thanks in advance!
