Fatal system error 0xc0000221

DKK · Nov 9, 2012

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

Please take a look at the Steps to Resolve Problems Preventing Windows Vista or Windows 7 From Booting and post back as you proceed through that guide if you have any questions. Let us know after each step what the results were so we can decide whether to provide further steps.

Best wishes you find the link helpful.

Also, when running SFC /SCANNOW from the recovery options, you will need the following command:

Code:

sfc /SCANNOW /OFFBOOTDIR=d:\ /OFFWINDIR=d:\windows

The above assumes Windows is installed on D:, but you should determine what drive it is actually on. It may not be on C: as it is in Windows since the recovery options see the partition table differently than Windows does.

Code:

dir c:\
dir d:\
dir e:\
dir f:\

The dir commands can help you find the drive that has the Windows directory on it.
