Yes it's 32bit. But apparently it's a windows problem. It would keep getting hung at "Completing Installation" stuff. I tried all of the following: Plugged a USB mouse and kept pressing a button Partitioned using BootCamp, and on the drive select screen I formatted the disc. On drive select: pressed "delete", then "new" on the BootCamp partition Used a brand new disc Fresh install of Snow Leopard Was wondering if anyone else have different options to try? I have installed Windows 7 on bootcamp twice before on this macbook pro and it worked flawlessly. I am starting to think it might be a hardware interference.
