Answering my own question in case anyone else has this problem.
While looking for my original disks that came with my HP pavillion dv6000, I found a paper that said "Restore Your System Without Discs." My notebook did not come with discs. I was supposed to burn them from the computer.
BUT - it also said "To repair or restore from the hard drive, restart the computer and press F11 when prompted." So I did, and it brought me to the Recovery Manager. From this wizard, I was able to do the chkdsk. I chose for it to scan the Windows partition. The computer found and repaired loads of bad clusters. When I clicked "next," the computer rebooted, configured the updates and started perfectly! Whew!
