Windows 7: Formatted drive lost bootmgr

Formatted drive lost bootmgr

I have a:
GA-MA785GMT-UD2H AM3 mobo
AMD Phenom II X2 550 Black Edition Callisto 3.1GHz
G.Skill 4GB DDR3 1333
Windows 7 OEM

I was having issues getting the drivers installed, so I did a format on the HDD. Regrettably I lost the bootmgr. Now I have gone in and done the repair through the System Recovery Option and through the command prompt by trying to rebuild the bootmgr by entering in bootrec /rebuildbcd. When I did this it said it was successful; however, it still says the bootmgr is missing. Please help. I don't know what to do now.

Boot the Win7 DVD or Repair CD to run Startup Repair up to 3 separate times with reboots, to repair or rewrite the MBR to Win7.

If you need to download the Repair CD: Download Windows 7 System Recovery Discs — The NeoSmart Files

I'm not sure I understand why you expect Win7 to start up if you formatted the HD. Did you run full factory Recovery and it still won't boot? What did you format exactly?

The only reason that Startup Repair will not work to eventually repair/rewrite the MBR to Win7 is if it is not marked Active for some reason. To find this out, you can download and burn to CD free Partition Wizard bootable manager, boot into it to check Win7 is active. If not, rightclick Win7>Modify>Set Active.
