Moving BOOTMGR and Boot to other partition on some disk

Partition D:\ contains an old Windows installation and is during the installation of the Windows 7 I currently use (C:\ partition) still marked as Active and System.
Now I’ve tried to copy the Boot folder and BOOTMGR file from my new Windows installation disk in the root of C:\ and after that run a Startup Repair, this didn’t solve the problem. Also using a command-line to mark C:\ as Active did not work. At boot up the BOOTMGR and Boot folder in D:\ are still picked first.
The problem is both partition are located on the same disk, so disconnection one is not an option.
Any solutions on how to make the BOOTMGR and Boot folder in C:\ the first to be recognized at boot up?
Thanks in advance.
Answer #1
Delete all the files related to bootmgr from D: and mark it as non active. After that do a startup repair by booting via a Windows disc.
Answer #2
the boot partition has to be a “primary” partition and set to “active”
a boot CD like “Hiren’s BootCD” or “Active Boot Disk” can help with that
then insert your 7 disk and boot to repair console
google “bootrec” and see how to use it to rebuild your “BCD” (boot configuration data) in repair console
another console command to check out is “Bootsect”

never done what you are trying to do exactly but these commands should help
just remember that drive letters are assigned by the OS and the bootloader can juggle them
before loading the OS the PC works with partition numbers
