Blue Screen of death after SID Change, can't use system restore

BSOD info:

*** STOP: 0X000000F4 (0X000000000000003, 0XFFFFFA800ADB2B30, 0XFFFFFA800ADB2E10, 0XFFFFF8000318e7b0

When trying to use system restore, I get "you must enable system protection on this drive"

however, when I try to do this from command prompt using a windows 7 cd "%systemroot%\system32\restore\rstrui.exe" I get that the restore service was unable to be started

Thanks in advance!
