Hi, Ive got 2 hard drives which I use for Hackintosh and ive got a spare 1 which I want to use for win7 but when I try to install win 7 it says it cant install because its a GUID partition scheme. Should I format the drive? To use windows do I need to change the drive settings in bios from AHCI to SATA?

For the first part, yes you have to format the drive to fat32/NTFS.

I don't keep my win7 or XP installs connected to my PC while I'm attempting my hackintosh install, as the last time I did that it killed my mbr loader somehow.

I just finished installing Win7 on a second drive. I did format it with GPart as NTFS, I did not change bios to sata, you may have t but I kept it set to AHCI. The only thing with threw me for a loop when I was done was I could not get my Hack to boot. It would just boot straight into windows. If this happens to you don't panic and start messing with Chameleon reinstalls or mbrs. For some reason on mine, it changed my boot disk (not device) in my bios settings. I had to change it back to boot from my osx install. And then had my chameleon and all my boot options back. However, I find installs are like snowflakes, no two are exactly alike. But like the poster above said, if you want to unhook your mac drive prior to, feel free.
