Recently, my sister dropped off her HP Pavilion dv6 laptop. She told me it had a few viruses that were quarantined...but couldn't be removed. Her school requires Symantec Endpoint Protection to be allowed on the network...so I wasn't surprised that the infections couldn't be completely removed. She didn't have the power cable with it at the time, so while waiting, I removed the HDD, plugged it in to my computer using an external USB Thermaltake dock. I ran MSE on the drive, and it found three viruses, including one listed as a boot virus, and successfully removed them. A second scan came up clean.
Now, here's the problem. I put the drive back into her laptop, and it won't boot. I get to the Windows 7 splash screen, and after the glowing orbs circle around, it blue screens. This happens under a normal boot, and all safe mode options.
I ran the various start up repair options, everything from the actual start up repair, to the bootrec commands, to sfc, etc....each several times in a row without any luck. The partitions are detected and accessible, but won't boot. What else can I try? My last step is going to be to image the drive and start over, but I'd like to avoid this.
