i have a new pc, i tried to install XP MCE on it and it crashed. I had already set up the partitions. When I now try and install on it again I can only see the small C: partition that I created. I have no OS installed on this machine and I need to clean the drive and have the full 320GB available again.
I'm also having trouble cos when i try and install Vista Home Premium x86 i get to the point where it asks me where I wish to install and when I scan no drives (drivers?) can be found.

I need help with this guys. Please give me your best.
