Windows 7: Move Win7 to XP partition

Move Win7 to XP partition

I have a 6 year old laptop running XP. I installed Windows 7 on a logical partition, just to see whether it would be OK on this machine. After locating the right drivers, I now have a basic installation with all updates in place, including SP1. I have made several images using Acronis TrueImage. Now I would like to delete XP and put Windows 7 on the XP (primary, system) partition.
One way to do it:
- restore my image to the XP partition (this would leave the MBR intact, I suppose)
- delete the first BCD entry with EasyBCD
- change the drive letter of the second BCD entry to C:

Or would it be safer to do a new installation of Windows 7 on the XP partition, restore the image and delete the first Windows 7 plus the BCD entry?

Thank you for your thoughts!

See screenshots for EasyBCD and EasusPM output.

Couldn't you just keep Windows 7 where it is and dump the XP partition?

Then expand the Windows 7 partition to take up the space formerly occupied by the XP partition?

No reinstall. No imaging.

Yes, thank you, of course I have considered that. Perhaps for sentimental reasons I like to have my OS on the C: primary partition. And the XP partition is "system", so I think I cannot delete it.

Yes you can delete XP and recover its space for Windows 7 although you must first convert the Logical partition to Primary so it will mark Active to receive the System boot files.

However apparently you incorrectly installed Windows 7 from the XP desktop which locked out the C letter so Windows 7 could not assume C whenever booted as it does when correctly installed from boot.

If you don't mind running Windows 7 on D, then rightclick on it using free Partition Wizard
bootable CD to Modify>Set partition to primary, click OK. Video help on how to set partition as Primary or Logical.

Rightclick again on Windows 7 partition to Modify>Set to Active, OK.

Next click on Win 7 Disk # to highlight it then from Disk tab Select Rebuild MBR, Apply all steps.

Reboot, if Windows 7 doesn't start on its own boot into Windows 7 DVD or Repair CD to Startup Repair - Run 3 Separate Times until Windows 7 starts on it's own and holds the System Active Boot flags.

You can now boot back into PW CD to rightclick XP to Delete, OK. Then rightclick Windows 7 partition to Resize, slide left border to left to take up deleted XP space, OK, Apply both steps: Partition Wizard Move/Resize Partition Video Help.

Have DVD/CD standing by in case you need to repair after resizing on the boot sector.

Thank you, Greg, for your extensive reply. I tried to convert the logical partition to primary with EasusPM, but it refused to do so because it's a boot partition. If Partition Wizard can do it, it would be a simple solution.
I'll let you know what happens.

I couldn't have been more clear that you need the PW boot disk, even providing a download link and video.

Easeus and all other partition managers can fail - installed or boot disk - while PW boot disk (not its installed version) has never failed in countless thousands of operations we've helped with here.

You cannot convert to Logical the booted Windows 7 partition while it's running.

Actually, you don't need a boot disk. I just "ordered" the conversion to primary, PW asked for a reboot and applied the change before starting Windows 7. After that I deleted the BCD entry with EasyBCD, formatted C: and all was well. I can even change the drive letters with PW, if I decide to do so. This really is a very good program, thank you for pointing that out to me, and thank you for your help!

But you need the boot disk if you want to insure against Failure.

As I said in the second paragraph all installed partition managers except Disk Mgmt can fail with catastrophic data loss. Only PW boot disk will not fail.

So you do need a boot disk unless you don't mind working without a net. You were simply lucky.
