I crashed my computer hardcore, and tried to reformat it. I have a Sony Vaio and I inserted the Windows XP System recovery CD and got to the part where it began restoring drive C but then a window popped up saying "Disc Access:Sense Operation Failed". When I press OK it says "The Recovery process is incomplete. Your system may not operate properly" and then it restarts. I tried erasing drive C and D by repartitioning them, but now everything seems to be erased. I have a boot disk, and I tried using that but I don't really know how to work it. If anyone can help I'd really appreaciate it. Thanks.
