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?
