Can't install OS onto my laptop, please help!

Hi everyone,

I have an HP Probook 4530s that came pre-installed with Linux Suse Desktop. I tried installing Windows 7 Ultimate onto it but it wouldn't allow me, due to the fact that my HDD wasn't NTFS. I logged into Suse and found a program that allowed me to change one of my partitions to NTFS (I changed the largest partition to NTFS) -but I think the problem was that this was classified as 'logical' rather than 'primary'. After this, I managed to get through the first installation process for W7 but when my laptop did it's first restart during the process, it came up with 'Disk error, Press any key to restart' or gave me the option to boot from CD or DVD. So right now, I'm stuck and I could really do with some help - any would be great, thanks.
