Windows 7: How to move Windows 7 from one partition to another

How to move Windows 7 from one partition to another

I need help to move My Windows 7 installation from Drive F to Drive C without loosing all my programs and settings.

I have been running XP on Drive C for what seems like forever, and I wanted to keep it until I was satisfied with the new Windows 7. As it turn out, I really like Win 7 and have not gone back to XP since.

I see no reason to keep the XP installation anymore, and I could really use the free disc space that remains after XP is gone. So Here is what I want to do...
  1. Format Drive C
  2. Move Windows 7 from Drive F to Drive C
  3. Merge the remaining empty space on Drive F into Drive C
  4. Get rid of Drive F partition
Attached is a snapshot of my Drive Management Map

Any Help would be appreciated

The only way to change Win7 from F to C drive is to reinstall. It is stuck with the letter F because its installer was run from XP blocking out the letter C so that Win7 couldn't claim it as it does when it is correctly installed from a booted installer. In that case whichever OS you were booted into would have been lettered C.

If you don't mind keeping the current install on F you can mark it Active in Disk Mgmt, reboot into the Win7 installer or System Repair Disk to run Startup Repair - Run up to 3 Separate Times until Win7 partition is labeled System Active. You can then safely delete C (after backing up files you need) and if you want resize Win7 partition into its space using Partition Wizard CD Resize Partition - Video Help.

Thanks gregrocker... I had a feeling I would have to reinstall... But I'm wondering if I can just format Drive C:, do a clean install of Win 7 on it, and then create a disc image of Drive F: with my Backup software, and restore the image to the C: drive. That way, I could avoid having to spend literally Days reinstalling my programs. I could then format the F: drive and use Partition Magic to resize C. Would that be possible?

You could try doing that with the way you have it now. Never tried doing that yet but it could work. Give it a shot.

Still the best way is to reinstall. You can work on it and still boot into the other 7, when you`re good, just delete F.

After you delete F you`ll have to run startup repair.

You do have a windows 7 install disc, correct ?

To try that you wouldn't have to reinstall Win7 but use the imaging app's boot disk which gives the best shot at recovering the C letter.

When it offers the choice of drive letter choose Auto, also a Primary Active partition.

This will normally allow Win7 to find C to letter itself with, but in this case since it was installed incorrectly from another OS lettered C, I dont' know if it is correctable even by this imaging feature. But as Brian says, you can try.

Someone else like SIW2 or Wolfgang may already know this doesn't work. I kinda suspect it won't.
