Force SFC to Run
There is a system repair pending which requires reboot to complete. Restart
get to the repair computer either by F8 or the install cd
login and select command prompt
issue command
diskpart
then list volume
this is to determine the boot volume disk and your system volume
generally c:\ is the boot and d:\ is the system volume
chkdsk /r /f d:
once finished then we need to rename the pending.xml file
d:
cd \windows\winsxs
move pending.xml pending.xml.1
x:
sfc /SCANNOW /OFFBOOTDIR=c:\ /OFFWINDIR=d:\Windows
hopefully this will fix your none booting O/S
