Repairing an unbootable Windows installation with bootrec.exe
If the boot/recovery partition is corrupted or lost, you can modify your Windows OS partition to boot.
Boot from your Windows Vista/7/Server2008/R2/2012 media and choose the
“Repair Windows” option.
Open the command prompt.
Using diskpart, mark your Windows partition as bootable.
If your windows partition does not have it, copy the “boot” folder from the
installation media.
Run the following commands:
>c:
>cd boot
>attrib bcd -s -h -r
>ren c:\boot\bcd bcd.old
>bootrec /RebuildBcd
Reboot and Windows should boot normally. If not, return to the command prompt and run:
>bootrec /FixMBR
>bootrec /FixBoot
