I'm working on a windows 8.1 computer that had a virus that apparently attacked the boot record. It restarts in a loop unable to find Windows. I created a Windows 8.1 repair disk on a different computer, and booted to the USB drive. I tried the automatic repair but it would work. I also tried running refresh but it said the drive was "locked" (what does that mean?!). Finally I opened a repair console, and ran the following commands:
If I leave the USB repair drive unplugged the computer continues to restart in a loop the same as before; however, now when the USB repair drive is plugged in and I tell the bios to boot to the USB drive it will actually boot into Windows 8.1!
I cleaned the virus (I think?!) and everything appears to be working well.
Any idea how I can get the computer to boot normally without the USB repair disk?
I can re-install from scratch but I would like to avoid that process if possible. I have a Windows 8.0 install DVD; however, apparently the repair function will not work since the computer has been upgraded to 8.1.
