Downgrade Windows 8 to Windows 7

Warning you must have the uEFI/BIOS firmware setting in Step Three set.

NOTE: Check your manufacturer's uEFI/BIOS firmware manual for settings.

Make sure CSM is ENABLED, & set to UEFI boot.
Technical Note: UEFI BIOS vs. Legacy BIOS - YouTube

Also enable Boot Menu.

Things to check, Make sure you are doing, Work down this list
1) setting BIOS.
2) doing Step 11
3) booting DVD/USB in UEFI mode.
4) using a USB 2.0 port.
5) using Windows 7 x64.

Yeah, my BIOS is set such that UEFI is enabled, but secure boot is disabled. I made sure to do step 11 when creating the USB install drive. I booted the USB in UEFI mode, and am using the USB 2.0 port, and both .ISOs I tried are win7x64 SP1. It successfully loads the windows files, but freezes on the "Starting Windows" splash screen, before it loads the language settings.

I was able to install win7 in legacy mode, I just wanted to see if I could get it working with UEFI.
