I'm trying to install Windows 7 64 bit on the second partition of my harddrive, but when I select the second partition in the installation process, I'm unable to install onto it because

Windows cannot be installed to this partition. The selected partition is of the GPT partition style

Is there a way to install it without formatting the whole disk because I still need the system that's installed on the first partition?

You can install Windows 7 on a GPT partition if you boot the Windows 7 install CD in EFI/UEFI mode. If you don't have an EFI/UEFI BIOS, then you have to install Windows 7 on an MBR formatted hard disk.

There's indeed a UEFI option in the boot menu! Thanks. It's working now – user14412 Aug 10 '12 at 20:01
