I have a computer with Windows Vista Ultimate 32-bit. I think the file system might be corrupt. When I start the computer, I would get the Vista loading bar, and then I would get a black screen. Now when I start it, it gives me a screen to choose between normal startup and the built in startup repair program. If I choose startup repair, it freezes on the loading screen. Knoppix recognizes the hard drive and is able to mount it. If I try to use the Vista installation disk to repair the operating system, it freezes while running startup repair. According to Microsoft's help database, these are two signs of file system corruption. PcMinistry's EBCD doesn't have any helpful programs that support NTFS. Any help with this problem would be appreciated. It would also be nice if someone could find a bootable disk that has checkdisk on it. Thanks.
