how to change %systemroot% from G: to C: - drive letters correct
Posted on 2010-08-17
I have a client's computer which is booting from his USB backup drive, which has somehow been marked as active and has Windows etc on it. I did not set up the drive, and as far as I know, he thought he was just backing up his computer. The drive has been in use for 11 or 12 months. Drive C: is the drive it should boot from, and drive G: is what it is booting from. Opening the Run command and typing C: opens the correct drive. Typing %systemroot% opens G:
He reports that this just happened two days ago, and if the USB drive is not connected, it won't boot. Is there somewhere in the Registry I can change the drive letter for the %systemroot% ? I don't think MS KB 223188 applies, because the drive letters are correct.
