Problem with mup.sys on XP

[cbailey]

All of a sudden, my Multi-boot XP PC stopped booting. When I tried going under safe mode, it seemed to stop at mup.sys. I read a solution to stop mup.sys from loading using the recovery console. However when I try to use this application, the PC locks up after I select the disk number. It also locks up when it searches for existing install of Windows, so I can’t overwrite the existing files. A search of the system doesn’t find this file.

Disk diags show the disk is error free. I can get to the XP partition through Linux.

Am I SOL and have to format and start all over or does anyone have any other ideas.

Thanks

Poor mup.sys, as it is the last visible driver loaded before XP enters protected mode. It is unlikely the actual problem.

Can you do a repair reinstallation of XP?

I tried that, when the install is looking for a previous install, the PC locks up.
