WinPE boots as X
So best I can figure is you are Booting to a partition with the PE Boot.wim applied
Thus it is now a bootable system partition and boots as C

Yes, exactly. I am trying to figure out how to mod the registry to specify the system drive as X: (Many people have had it be D:, so why not X:) This means replacing all X: with C: or following microsoft's procedure to change the boot drive letter from something back to C:
I CAN access the desktop with Utilman hack, which is that ease of access button down there, to launch cmd, then explorer. I can't use repair DVD because it won't detect it (Yet it could actually repair it)
Thanks
