Windows 7 - another partition question

Here's the scenario: I have a 1TB disk with several partitions on it.
#1: Primary partition with Vista on it.
#2: A 500GB primary partition used as storage/backup.
#3: A 50GB partition encrypted with Truecrypt, Logical drive
Now, I want to create a new Primary partition at the end of the drive, so I can install another copy of Windows 7. Notice my 500GB storage partition does not need to be Primary, but it is, and I cannot create any more Primary partitions. How can I change the storage partition to a logical drive, and have my new partition be Primary?

You may have figured it out otherwise, but I thought you could have 4 primaries? Or do you have other drives in the PC?

A picture is worth a thousand words.

The little 5GB free space in the middle is wasted space. If I create a new volume there, it is primary.

you do not need the new partition to be primary to install another operating system on it
you all ready have7 installed so just install the new operating system on the new partition and dual boot

Do you have enough free space outside of the 500 gig primary to temporarily offload everything in it and then delete it and remake it as logical?

It looks like everything to the right of it is empty.

Not sure you can change primary to logical directly--maybe with a fancy tool?

Seriously? I thought the partition had to be Primary to install Windows on it.

only the boot partition

Okay, thanks.

you should just create a new partition on your 300 gig c drive

Thanks guys, it worked like a charm.
