System Details:

Asus Sabertooth 990FX motherboard

AMD FX-8120 CPU

16 GB DDR3 1600 Corsair Vengance RAM (4x4)

EVGA Nvidia GTX-560Ti video card

2x Dvd/cd rw dirves

1 Bluray RW drive

1 Orico USB 3.0 & eSata panel

1 Sabrent floppy bay card reader w/USB 2.0 port

760W pc power & cooling PS

OCZ agility 120GB SSD (Windows 7 Professional 64bit installed in an approx 80gb partition, NTFS. There is also a "System Reserved" partition shown in disk management at 100mb in size, also NTFS)

That leaves about 32GB usable free, un-partitioned space in which I hoped to install Ubuntu.

However when I run the Ubuntu 11.10 AMD64 installer, it doesn't show there is even an operating system installed. It just shows the entire drive as free-unpartitioned space.

Just not sure what to do here. I was thinking about using the Wubi installer, but i don't know about that. Is the performance reduction pretty drastic?

Thanks,
