Ok, so my mothers computer (Hp Slimline s5000 series) started showing signs of being infected. It ended up being a lot worse than I expected, the computer would boot to windows than most of the time explorer would crash. We were able to backup her personal files, and I just planned on wiping the hard drive and partitioning it with my own rig. I am a Comp. Ed. student and get a free copy of Windows 7 Pro through Dreamspark, so I planned on downloading it on my pc and then use a virtual drive to run the setup and install windows on the new partition I created on her hard drive, the install finished and Windows booted on my pc through her hard drive. So far I had no problems, until I installed the hard drive back into her pc and it wont boot. The bios detects the HD as the prim. boot drive, but it wont boot. Any thoughts?
