I had installed Windows 7 on a separate 20gig partition, and I'm absolutely loving it! Plus I can now dual-boot, with my original WinXP residing on the C: drive. But I'm running out of disk space on D:, and I was able to shrink C: and expand D:.

But now I would like to make D: not just a Boot Partition, but an Active System Partition, without losing my ability to boot into Windows 7 (since it was created on a separate D: partition, not the current Active System C: Partition).

Any advice?

Why do you need it to be an active system partition? Both OS's boot fine? – Moab Nov 12 '11 at 23:10
I'm so confused trying to figure out what this guy wants. – surfasb Nov 14 '11 at 4:49
Only 20gb for Windows 7? I figured you'd run out soon :D – sinni800 Nov 16 '11 at 17:30

There is a lot of programs on the markit that can extend a partition, using the free space from a different partition on the same HDD. One that we use in our office is Easeus partition master.
