Installing Ubuntu on an EFI-based Intel system

[Robert Pruyne]

Not to over simplify, but sometimes it's the most basic things we forget about.  I would guess it's a matter of the hardware to the CD got messed up.  Unless you reflashed the bios, I don't think the problem is there.  I don't think this has anything to do with EFI.  
 
1.)    Did you knock the cable partially off the CD or off the Header for on the motherboard?
2.)    Did you knock the power off the CD Drive?
3.)    Does the CD drive work still?
4.)    Try moving the CD cable to another header on the MB. Try changing the cable to the CD. Try another CD Drive.  
 
Sometimes if the bios doesn't see a device it won't list it.

Subject: Installing Ubuntu on an EFI-based Intel system
 
I've installed Ubuntu (and other Linuxes) on various workstation-class systems for years, but I've never done an installation on one of the new EFI-based systems before, and this one did not go well. I need help recovering.
 
I stuck four large SATA hard drives, a SUPERMICRO MBD-X9SCA-F-O Server Motherboard, an Intel Xeon E3-1230 Sandy Bridge Quad-Core Server Processor, a bunch of memory, a power supply, and an optical drive in a box. I configured the disks as a RAID 5 in the BIOS utility, told the BIOS to boot the CD, and started installing.
 
Halfway through the install the machine signaled an overheat condition and stopped. Turned out I hadn't installed the CPU heat sink correctly. Doh! With this fixed the machine seems OK, but I can't figure out how to boot the CD again. The optical drive isn't an option in the BIOS Boot section anymore. Do I have to break the RAID?
 
Thanks for any advice.
