Try and boot in safe mode, then uninstall the service pack. Believe it or not, the uninstall does work!
I still dont put SP2 on alot of machines unless they came shipped with it originally.
What happened to yours ma12.5? Hard disks can still have the data recovered after they've failed.
well... i was advised to do a partial system restore which deleted somethnig it shouldnt have and so wouldnt even start up after that. so it went away for repairs etc, got it back today and they have replaced the hard drive without even a phone call to let me know all my stuff from it would be gone and they had already had it for 3 days before i called them to see where it was!!
not happy
ahhh man you have been DONE there, like m1ck97 said, backup the stuff you need inc drivers then fresh install !
is it pc world ? Also you can get the data back if they didnt replace the hard drive, file scavenger is the program i sometimes use.
