Please help me change the active partition

My ultimate goal is to eliminate drive C altogether. Win Xp is installed on C ,Win 7 is installed on E, and I would like to set e as the active partition, remove all the files from C and uninstall xp. Please help me out!
I have attached a screenshot of my Disk Management.

Welcome to Windows Seven Forums.

Please read this tutorial on how to use Partition Wizard: Partition Wizard : Use the Bootable CD

However, before you go down this road I would clean up your current disk layout.

Personally, I would wipe the hard drive completely and clean install Windows 7. The reason I suggest this is because it is recognised as best practice to install your operating system to a primary drive rather than a logical volume.

During the install, Windows will want to create a system reserved partition of 100 MB, which will hold the master boot record and will become the active partition.

Windows will then be installed and will automatically give the partition it is installed on drive letter C.

Does Windows 7 itself show as C drive when you boot into it? It should do this unless it was incorrectly installed from the XP desktop.

If not then I would definitely clean reinstall it from boot after deleting all partitions on the HD: Clean Install Windows 7

If so then you can use free Partition Wizard bootable CD to convert Windows 7 partition to Primary, rightclick to Modify>mark it Active, Apply steps. Then boot into Windows 7 DVD Repair console or Repair CD to Startup Repair - Run 3 Separate Times.

Once it starts on its own and lists the System Active flags, then you can boot back into PW CD to delete XP partition, rightclick Windows 7 to resize and slide its left grey border all the way to the left to move Windows 7 into the preferred lower HD space, then slide right border where you want it.

No Win 7 comes up as Drive E, Win XP was first installed on drive C. It became unbootable in the sense that I would get a blue screen eventually. I have all my files on Drive E, and would prefer to keep them rather than reinstalling altogether. Is there a way around this ?

The only way Windows 7 when booted will see itself as anything but C is if the Windows 7 installer was run from an OS and not booted.

Yes, you can continue to use Windows 7 on E and delete XP if that is what you want.

If you want to get rid of XP and just keep Windows 7, you have a couple of problems:

1. You XP partition contains the bootmgr which also boots Windows 7. if you delete the XP partition, Windows 7 will not boot any more. You would have to move/fix the bootmgr on the Windows 7 partition.

2. Your Windows 7 partition is not a primary partition. If you want to make it active, you have to first make it a primary partition.

If you want to do that and need help, post back.

Boot free Partition Wizard bootable CD, rightclick on Windows 7 partition to Modify>Convert to Primary, click OK.

next rightclick on Windows 7 partition again to Modify>Set to Active, click OK.

then click on Windows 7 HD to highlight it, from Disk tab select Rebuild MBR, OK, Apply all steps.

If Windows 7 doesn't start at reboot, boot into Windows 7 DVD Repair console or System Repair Disk to Startup Repair - Run 3 Separate Times.

Once Windows 7 starts on its own, confirm in Disk Mgmt it holds the System Active flags.

If you want to recover the XP HD space into Windows 7, boot PW CD again to rightclick XP to Delete, OK. Then rightclick Windows 7 partition to Resize, slide left grey border to the left to take up XP space, OK, Apply all steps. You may need to Rebuild MBR again or run Startup Repairs if Windows 7 doesn't start.

Back up your files and a Windows 7 backup image beforehand.

1. Download and burn this program to CD - it is the last entry on the webpage.

2. Load this CD (you may have to change the bootsequence in the BIOS)

3. Highlight your XP partition, click on the Partition tab and go to Modify, then on deactivate

4. Highlight your Windows 7 partition, Partition tab > Modify > activate -- then click Apply under "Operations pending" on the bottom left.

5. Now you can fix your bootmgr on the Windows 7 partition: Bootmgr is missing - Fix

Hmm, just saw that Greg had explained that already - better read that

Thanks for all the input! I have set the Windows 7 HD as Primary and active. I highlighted the win 7 HD, but I cannot select anything from the Disk Menu.
