I have a Dell Inspiron 660s PC. Last week the mobo failed and I ordered a new one. After replacing the bad part, the system starts, starts loading Win 7, but then hangs. I wanted to do a repair install, but there wasn't an option in the Recovery partition. So, I tried to run an upgrade via DVD, that failed as the update needs to run from within Windows. The isn't a valid backup for the drive, so I can't restore to defaults as there is a POS program and database on the drive that can't be overwritten. Am I out of luck?
