I'm trying to setup a dual boot system with Windows Vista 64 (already installed) and Ubuntu 10.10. I added a new drive which is identical to the one Vista is installed on. When I boot into the LiveCD I can see and mount the second drive and edit it in Gparted. However, when I use the installer it will only bring up the drive that already has Vista installed.

I've tried everything I know. I'm not sure if its a BIOS setting or something else I've missed.

This would be best on the Ubuntu StackExchange. – Matthew Flaschen Jan 12 '11 at 5:55

Have you clicked on the list box and selected the second drive? By default, the installer will show the partitions on the first drive.

Yes, I've tried all three install options and all three list the drive and partition where Vista is install, but does not list the second drive. – atodd Jan 12 '11 at 4:11

Sometimes if you have a newer motherboard the drivers for chipsets managing storage would be not included in Ubuntu LTS editions.

Try to boot a live session and start a terminal session (or to switch to the console with CTRL-ALT-F1) and issue:

$ sudo os-prober

You'll probably see a probing error which could be the reason why your drive is not taken in consideration. It's quite likely that your second drive has leftovers of a RAID configuration, in this case it's sufficient to do:

$ sudo dmraid -rE

(-r = raid, -E remove metadata) and confirm the operation. Start the installer and you should see it.
