Windows 7: Relocating Windows 7 Boot Manager

Relocating Windows 7 Boot Manager

Hi All,

I am using a PC that originally had Vista installed on it. I then added a separate hard drive to try out Windows 7 a while back and love it.

So I would like to re-allocate the original Vista drive to something else ( or even move it out to a different system )..

But alas.. the bootloader..

As you see, the new drive with Windows 7 is C, and Bootloader with Vista are on D.

How can I make my existing C drive stand alone so that I could remove D and the system continues to boot ?

Win 7 had been operational now for 4 months with tons of software. Dont really want to reinstall ..

Thanks !!!

Please post back a screenshot of your full Disk Management drive map, using the SNipping tool in Start Menu, attach file using paper clip in reply box.

Then we can give you the exact steps to remove Vista and recover it's space and MBR into Win7.

I think this logic should do the trick:

Copy bootmgr, bootsect.bak and boot-directory’s files from d: to c:

bcdedit /export c:\Boot\BCD
bcdedit /store c:\Boot\BCD /set {9dea862c-5cdd-4e70-acc1-f32b344d4795} device partition=c:
bcdedit /store c:\Boot\BCD /set {b2721d73-1db4-4c62-bf78-c548a880142d} device partition=c:
bcdedit /store c:\Boot\BCD /set {466f5a88-0af2-4f76-9038-095b170dc21c} device partition=c:

From the Windows 7 dvd

Set HD0 partition 1 active:
select disk 0
select partition 1

Finally remove Vista from the loader:

bcdedit /delete {318cb2f8-ab6a-11dd-bb33-d4d370134381} /cleanup
