Video help on how to set partition as Primary or Logical.
now press apply so it does what it should do.
System won't boot succesfully afterwards.
Boot from win7 install dvd or system repair disc and do a startup repair 3 times with reboots in between.
Startup Repair
Now boot normally.
Now you can delete or format the partition within disk management.
HOW to mark it as active there is no option ...

You have to first mark the C partition inactive. There cannot be 2 active partitions on one disk. Do all that with the PW bootable disc. see above.

I have been monitoring this thread and believe it may be beneficial if you have a friend help you with this process. It can get confusing and usually two heads are better than one.

Just my .02 pennies.

It won't boot now, because bootmgr and bootmenu are not on active boot partition! Do a startup repair 3 times, as told you a few posts before

You could not have formatted XP with the Win7 boot files residing there. It would have refused formatting due to the presence of boot files, or else 7 would not be able to boot and C would not have the System flag.

So you likely still have XP on C.

If you would like to have Win7 on C as most do, then I'd reinstall to C after moving any data off of the HD. During install delete it and and other partitions not needed, then repartition or let installer do it for you by clicking Next.

If you want to keep Win7 on D then convert to Primary, mark it Active, boot into WIn7 installer to run Startup Repair - Run up to 3 Separate Times.

You can then delete C in Disk Mgmt which is how an OS is correctly removed, then either create a new Data partition there, or resize D into the space using Partition Wizard Move/Resize Partition Video Help.

Feel free to ask back any questions for clarification.
