You do need a windows 7 disk to quickly repair this issue. In this case the bootmgr was jacked up by a virus.
Boot to windows 7 disk.
Select Recovery Repair Options.
I normally do not use the startup repair option. The auto repair is a hit or miss. But try it if you want too, it could fix it.
But to save time on the Recovery Menu choose Command Prompt.
And type in:
bootrec /FixMbr (Press Enter) You should get a confirmation "The operation completed successfully "
bootrec /FixBoot (Press Enter) You should get a confirmation "The operation completed successfully "
bootrec /RebuildBcd (Press Enter)
Scanning all disks for windows installations.
Please wait , since this may take a while...
When finished you should see
Successfully scanned Windows installations.
Total identified windows installations: 1
Add installations to boot list? Yes / no / all
The operations completed successfully.
This did work in this case, so I'm stopping here.
