When I boot the computer it reads the hard drive enough to start booting windows but then gets a blue screen. when I boot off of the cd it says it doesn't regognize if the drive is ntfs or fat, it just says unknown and doesn't give me the option to repair the existing windows install. I already tried fixmbr that didn't work. The weird thing is, when I boot off of bart pe I can read the data on the drive just fine. Is there anything that can fix this without formatting or am I just going to have to format?
