Move Windows 2008 Bootmgr to Another Partition

Ran into this problem when the bootmgr was installed on a 100MB partition. Windows assigned the partition (this was the first partition on the disk) the drive letter D:. I needed to move the bootmgr to the C: drive and get rid of this partition. Below are the very rough steps (recorded here for my own purpose).

1. Copy the boot files (bootmgr, BOOT folder, BCD will error out, that's OK, we'll address that later) from the current active partition to the partition you want to be active
2. Reboot to the machine to the install disk
3. When the computer boots into the install, choose to "repair windows"
4. Click next then choose command prompt
5. run bcdedit /export c:\BCD
6. ren c:\boot\bcd bcd.old
7. Bootrec /rebuildbcd
8. Run Diskpart (select the disk then the partition that you want to be active) and mark the new partition as active using the ACTIVE command

Reboot and that's it.
