I'm installing Ubuntu onto a HP Proliant DL360 G7 server, which has a hardware Smart Array RAID controller that is not compatible with Ubuntu.
HP say the RAID controller needs to be disabled in the BIOS in order to install Ubuntu.
The problem is, with the RAID controller enabled the installation can see the hard drives to install on but then can't boot, with it disabled the installation can't see any hard drives.
UPDATE: Ubuntu installs with hardware RAID active but hangs on "Attempting to boot from hard drive C:"
I've been advised to put the server into rescue mode and reinstall GRUB but holding down shift at any time during boot doesn't bring up the GRUB menu (I've tried it many times at different points), the Ubuntu Live USB does not have a rescue mode option.
