When I try to install 10.4 on my hard drive, I get all the way to the "Prepare Partitions" menu and there are no disks listed and all button are grayed out.
I am installing on an EVGA X58 motherboard with Intel ICH10 and I have AHCI enabled.
Does Ubuntu support AHCI? Do I need drivers to install?

I found a thread while waiting for a reply and it was suggested to run a few commands.
I ran these as suggested:
sudo fdisk -l
and here are the results:
ubuntu@ubuntu:~$ sudo fdisk -l

Has this disk been used in raid before? This usually happens when there is raid metadata remains on the disk.
If you are NOT running raid, you can remove those settings by booting into ubuntu live mode, and in terminal executing:
sudo dmraid -r -E /dev/sda (if your disk is not called /dev/sda, change here)
If that asks you if you want to remove settings, that was your problem. Do it, and the installer will see the disk just fine.
Also, I notice there is no unallocated space on the disk. It's better first to boot windows and shrink the partition you plan to shrink, to make space for ubuntu. Leave the newly created space as unallocated. Boot windows few times to do its disk checks. Then boot with ubuntu cd and install.
In vista and 7 you can use Disk Management for resize. XP does not have the tool for resize.

oops, I forgot to post here that I fixed it already. It was the dmraid issue from when this disk was in RAID 0 over a year ago and several OSes ago. I guess formatting or even unallocated the drive doesn't get rid of the RAID info.
I've always used Ubuntu to shrink the drive and auto allocate the disk for me. I do notice it usually uses half the drive and when I installed it on my 1TB drive, it gives way too much to Ubuntu. Maybe next time I'll try my Windows 7 to re-size the disk so I can get the right size I need.
