Gateway vista worked fine yesterday. Upon booting today, I got the scrolling bar for a long time, then the fatal error stated in title.Booting in safe mode gave me same error. Did system repair at least 6 times only to get error code 0xo, disk is corrupt. I keep getting these errors repetitively. This is my work computer that is used for my business, so I need to get it up and running, or at least be able to backup files. My backups are not appearing on my thumb drive - don't know why. Upon doing system repair using CD, it could not find a restore point which I just made 2 weeks ago. I'm desperate as this is used for work with all files on it. Can't get to a command prompt to run scannow. Tried running scannow from repair disk at an x:/ but said it couldn't be ran. Help. Thanks, D
