Additional info - tried the FixMBR command, continued to reboot itself. Tried the steps at
http://tech.icrontic.com/articles/repair_windows_xp/, continued to reboot itself.
In the midst of all of this, hit some key that allowed me an option of "turn off automatic reboot" which I did. I then rebooted, got a blue screen that gives the following error:
A problem has been detected & Windows has been shut down.......
Technical Info: STOP: 0x0000007F (0x0000000D, 0x00000000, 0x00000000,
0x00000000)
I See a lot of info on the web in regards to various reasons for this error,
but none seem to apply to this situation. Any suggestions appreciated.
