I'm trying to get 12.04 LTS 64-bit up and running on a Dell PowerEdge T300 Server with the Dell SAS 6/iR RAID controller (LSI SAS1068E chipset).
Ubuntu installs just fine, doesn't report any errors, sees the RAID mirrors as drives, everything seems normal, but fails to boot up after the installation. It reports
no boot device. The
/boot partition is on
/dev/sda1 and is marked as bootable, and when I installed Ubuntu, I told it to install grub to the MBR.
Any suggestions for what I should check next?
