Hello,
I received this message when I booted from a Win 7 restore disc:
OCC9 Unexpected I/O error has ocurred. As it loads the files, it just stops. What is going on?
 



Obviously cannot read the disk. If a cd restore disk, make sure it is clean and not scratched. If on hard drive, run chkdsk /r on that drive from CMD prompt

EG, chkdsk x: /r (where X is your hard drive.)
