hi,
i have a user with a windows xp pro system, and he decided to clean up the system himself by uninstalling a program, when system restarted its in a boot looop.

it gets to the blue windows logo screen with the rolling blue bar, then the blue screen comes up, then it restarts, to the loop.

when i tried starting into safe mode, it got to a certain point [mup.*) and restarted again, its not getting past this point?
ideas
i have the windows xp pro cd rom, and a flash drive and a ubcd4win cd handy...?
thanks

Press F8 after BIOS POST, choose Last Known Good Configuration, if that doesn't work using the same procedure try choosing System Restore and roll back to a date when it was functioning properly.

Insert the Windows XP cd and then select install Windows XP, confirm that you want to install Windows XP>F8. Then select to "Repair", not a new installation ** be careful **
You will have to re-enter the license key and your install will go back to files on the CD (meaning that if your CD has SP1 or SP2, you will have to reinstall SP3 and all the other updates).

I hope this helps!

Guys, thank you.
i ended up doing the 'boot to windows cd rom, and installing and the doing the repair (in the old days this used to be called a 'dirty install' to install over itself and try to keep the data and apps installed intact)
it asked my for the license key, i needed to activate again.
but at least windows is up, the apps are there, and now im doing all windows updates again.
thanks experts
