    One avenue would be to insert the installation DVD and choose Repair my PC. Quite often you do not even have to do the Auto Repair. The missing MBR is seen by the installer and fixed. Otherwise choose the Repair option.

    Which OS was installed first?

    Boot your Windows 8 disk and choose repair.

    Thumbs up

    I have a fairly new Windows 7 64-bit workstation (age less than 1 year) and I installed Win8Pro on a separate disk.

    I used a Win7 install DVD (for 64-bit) to repair (startup repair) the dual boot BCD when I hit a problem. This is discussed in another lounge posting. It worked.

    Note that the "startup repair" option is gone from the Win8 DVD. Well, so are lots of other things as well (like see full map in the network and sharing center).

    I have startup repair on mine. Perhaps you should re-download the ISO and try a fresh burn.
