Legacy Boot doesn't work, I'm stuck in Windows 8

[saitamonje]

Hello everyone

I recently installed Win8 in my pc just for trying it out. Now I want to go back to my old Win7. But I can't, because UEFI won't let me.
I went into the BIOS and disabled UEFI for all devices and selected instead "Legacy OpRom" instead. But it didn't work. So I tried disabling Fast Boot too, but didn't work neither. And I tried lots of combinatios around the options in my BIOS, even updating it today, but nothing seemed to work. I have to say I tried this before I had my GPU and the same was happening.

Any ideas about what could be the problem?

My pc specs:

Mobo: Asus A55BM-E with
CPU: APU 5800k @ stock
RAM: G.Skill Sniper 2133 Mhz
GPU: Sapphire r7 260x
HDD: Caviar Blue 1 Tb 64Mb

Thanks in advance, I really would like to go back to Win7

Secure boot - DISABLED
UEFI - ENABLED
Fast Boot - DISABLED

Then change the boot order to your bootable Windows 7 media first, boot from the DVD/USB stick, and install Windows.

Thanks for your answer, tried that but it just skips the USB stick and goes straight into Windows 8, it takes a little more time to start though. Could it work if I disable UEFI too?

Secure boot and Fast Boot are the two items that need to be disabled - you need to set the boot order to be the USB stick first, then the hard drive.
