Problem with installation to multiple physical disks

[dhopcroft]

My PC fails to boot when I make an installation across two disks.

Ubuntu 64 bit desktop 12.10 (It's all I had on hand, as bootable USB stick. But I can make another if this is the problem)
Motherboard is an Asus P9X79Pro


I have a new PC, with an SSD and a HDD, I want to use the following scheme to partition the disks.


On SSD (/dev/sdc)
/
/boot
/usr


On HDD (/dev/sda or sdb)
/home
/var
/svn
swap


The installation seems to go fine and no problems are noticed. However when I boot the installation, all I get is a flashing cursor top left of the screen.


I am thinking this is a problem with GRUB, But am lost as to what it could be.


BTW the installation works fine on either SSD only and HDD only, I only get the problem when I try and split the installation across two drives.

In the installation, where did you install grub to? If it is the only operating system on the PC, then it should have been to /dev/sda, not /dev/sda1 or 2 ect.

Also, do you know if your PC came with EFI hardware? If so, that will be the problem. Here is a handy documentation page about installing Ubuntu in EFI mode: https://help.ubuntu.com/community/UEFI

Thanks, It didn't occur to me the BIOS could cause problems. This is my fist PC with a UEFI BIOS, and particularly with this odd hard disk layout.

I have the settings in the BIOS set to to "something like" described in the link you gave. I'll have another go at installing later today. If I get chance :(

Cheers.

Thanks again. My system is now booting as I wanted it, the info on the linked page you gave was what I needed. Also I upgraded my distro to the latest (13.04) :)
