Windows 7: Very Specific Bootmgr Problem

I got hold of an official (legal) Windows 7 release through my college which has a deal with microsoft. This is not a beta or RC I am running. I have been running Windows 7 with no problems for 3 weeks now, and got all new parts and finally got rid of my single core cpu. put everything together, attatche harddrives, reinstalled and activated win 7 without error.

--I installed XP on one drive (drive0 labeled D and win 7 on the other (drive1 labeled C.
--i decided later that day after getting XP mode working that i didn't need the XP drive anymore and formatted it.
--I set the proper boot flags on the harddrive with 7 on it. but i get the "bootmgr missing" error, and have been unable to fix it. i used system recovery, and that put the MBR on the proper drive ( i also swaped the sata cables so Windows 7 drive is drive0 now) and i removed the other harddrive completely.

How do i fix the bootmgr with the recovery tools on the DVD?

Any help is much appreciated.

boot from the DVD hit Shift + F10 for command prompt and run bcdboot c:\windows command (assuming the partition with 7 on it is labeled as C:

it should put bootmgr on the C: drive

Thank you. I will be trying that as soon as I get back to my dorm and post telling if it worked or not.
