Windows 8 preinstall downgrade to Win 7: UEFI problems :/

I have a friend who has a HP Laptop with UEFI booting. Due to some unfortunate human error resulting in an unbootable system, I suggested and he agreed to installing Win7 ("I hate the big tile thingys"). So I attacked with Gparted. Wiped the whole drive. Set flags to boot. Set part table as MBR.



However upon trying to install win7, it still claimed I had a GPT style disk. Unable to install. The only thing i can think of I'm doing wrong is not changing the BIOS/UEFI to legacy.



My question is, if I enable legacy, somehow get the drive to actually be MBR, and use my X86 DVD, should I be good? Is there some common glitches people miss when dealing with GPT/UEFI? I need some help because he now has a blank laptop which I am responsible for.



Another question. windows 8 came installed on a GPT disk. So why does it say it can't install to a GPT-style disk, when I boot the install DVD?



Backstory : He locked himself out of windows 8 (forgot his password)... so he called me. Well, after trying to use the latest version of chntpw in UBCD5.2.6, i came to the conclusion i needed to wipe the drive and install windows 7. A little googling suggested using certain versions of chntpw, but i decided to not waste the time burning endless CDs.
