I downloaded Ubuntu 9.10 x86_64 and am trying to install it on a fairly modern system with a Gigabyte GA-MA770-UD3 motherboard. Ubuntu 9.04 installed fine and still will when I stick that disc in, but 9.10 doesn't see my hard drive (western digital 250GB). If I boot from the disc, I can install gparted and it does recognize the drive, but when I try to start the install process from the live disc, Ubuntu again doesn't recognize the hard drive.

I checked /var/log/messages and see this:

Nov 12 17:28:08 ubuntu activate-dmraid: Serial ATA RAID disk(s) detected. If this was bad, boot with 'nodmraid'.
Nov 12 17:28:08 ubuntu activate-dmraid: Enabling dmraid support
Nov 12 17:28:08 ubuntu activate-dmraid: ERROR: either the required RAID set not found or more options required.
Nov 12 17:28:08 ubuntu activate-dmraid: ERROR: either the required RAID set not found or more options required.
Nov 12 17:28:08 ubuntu activate-dmraid: ERROR: either the required RAID set not found or more options required.
Nov 12 17:28:08 ubuntu activate-dmraid: no raid sets and with names: "nvidia_ciiajheb-0"
Nov 12 17:28:08 ubuntu activate-dmraid: ERROR: either the required RAID set not found or more options required.

I checked my BIOS, SATA is enabled and is set to IDE mode, so there shouldn't be software RAID, but nonetheless, I added nodmraid to the boot line and tried again. It still doesn't recognize the drive. I checked /var/log/messages again and now see this:

Nov 12 17:49:38 ubuntu activate-dmraid: Serial ATA RAID disk(s) detected. If this was boad, boot with 'nodmraid'.
Nov 12 17:49:38 ubuntu activate-dmraid: Enabling dmraid support
Nov 12 17:49:38 ubuntu activate-dmraid: WARNING: dmraid disabled by boot option
Nov 12 17:49:38 ubuntu activate-dmraid: WARNING: dmraid disabled by boot option

Any ideas on things to try? I've tried all of the various BIOS settings for SATA. IDE,RAID, etc. Nothing seems to work.
