Partition problem Windows 7

[Inflamable]

I have a new HP Pavilion dv7 wich came with Windows Vista.

So... i really didn't like Windows Vista at all, and decided to install Windows 7.

I made a new partition and installed Windows 7 on that partition.
The problem is that I cannot delete the previous Windows Vista partition, or even format that partition.

I tried with the Disk Mannagement tool that comes with windows. I also tried with Partition Magic but there seems to be a compatibility problem with the OS.
Is there anything i can do?

GParted is a bootable disk management application that you can use to try and overcome this problem. Just be warned though, that you will have to manually edit your boot file.
