When powering on, hit F8 like you do to get into Safe Mode to get the Advanced Boot Menu. Instead of selecting Safe Mode there, select Command Prompt. From there you can run chkdsk, you can copy and paste your files to an external hard drive or flash drive, and you can run the command sfc /scannow. The SFC command checks for and attempts to correct for corrupt system files.
I booted the computer yesterday morning and received a windows-corrupt file dialogue box saying the file or directory C:\System Volume Information\_restore (lots of numbers here) corrupt and unreadable. Please run the Chkdsk utility.
I was unable to click ok close out or anything. So I booted into safe mode tried to reach command prompt to run Chkdsk and can't reach the command prompt because it gets stuck.
The last thing I have tried is to run a repair install from the windows installation cd. After two tries it gets all the way through the repair install it is stuck on the blue screen and says Windows is starting up.... with the hour glass for the mouse cursor.
I have run out of things to try. Need help. This is my business computer and can't really afford to do a complete new install of windows and lose a lot of information.
