You can't boot into the Recovery CD you made? If you can, you can run chkdsk or do a Startup Repair.
But you can download a Windows 7 SP1 .iso file online...try the following link, but you may have to check the net for a better site.
Link Removed
Well, tried it again and I guess it is downloading... didn't think it was because it said download time as more than 1 day. eek!I am downloading it from the link given right now. Maybe it depends on your locations.
Haven't really tried since we have no data we need to recover....this , \"again\", sounds like very bad sectors. Had this issue two months ago. Are you able to PULL any of the data off from Ubuntu. That will tell you if sectors are bad around the data and not just the OS
