Solved Inacessible C: Drive after Using NewSID

[JohnGrigg]

I just used NewSid to change my SID and after a reboot the c drive is inaccessible from startup repair.

Is their any way to undo this or have i just hosed my os.

I cant access system restore or anything in c drive.

Are you able to get into the Advanced Boot Options menu? If yes, one of the options is Repair Your Computer > System Restore which may get your computer back.

Just an FYI, NewSID was "retired" on 11/3/09. Microsoft apparently fixed the SID problems with the release of Vista and with XP w/SP2. I don't think there's any reason to use NewSID unlessyou're using a Sysprep image of XP w/SP1.
