Hum whatever drive you put or have in should be picked up by the BIOS if I am not mistaken and the install should "look" at what you have on board.

windows 8 64bit
 
 

i looked it up more and someone said it shouldn't be the drivers, that the disc is probably corrupt. im making another bootable disc, this time using windows 64 bit home premium. hopefully it will work

edit: it made no difference. any ideas?

edit again: so turns out it was just the iso I was trying to use. even though I tried 3 different ones, but all from the same location. once I switched to a completely different download from a torrent site, I had no issues. installing on my other pc as I type this...hopefully im not jinxing it right now lol

How are you activating Win7 on that Win8 machine?

If you have a license use the latest official installer for your licensed version from Clean Reinstall - Factory OEM Windows 7.

If you don't have a Win7 license, you'll need to buy one.

Make sure CSM is ENABLED, & set to UEFI boot.
NOTE: Check your manufacturer's uEFI BIOS manual for settings.
Take a look at this post.
