View Full Version : [ubuntu] Operating system not found during installation

October 29th, 2008, 10:28 PM
I am trying to install Ubuntu Server Edition 8.4 on a new whitebox system that has two 160gig SATA hard drives that I intend to use in a RAID array. The system also has a SATA CD/DVD drive on Port 0; the two drives are on ports 4 and 5.

When I start the computer, the system attempts to "Boot From AHCI CD-ROM", then reports "Operating System not found."

I have selected the CD/DVD drive as the first bootable device in the BIOS. The CD/DVD drive and both hard drives are shown in the BIOS.

I checksummed the ISO file; it's perfect.

The hard drives were already configured as an array using the Intel RAID utility. I deleted the volume to see if that might have been the problem. It wasn't.

I'm a noob to both Ubuntu and RAID, so I'm throwing myself on the mercy, and expertise, of the community. Thanks in advance.

Download a Knoppix Live CD and see if it boots:
Let me know

Found the problem -- the ISO image was burned onto the disk, rather than the files and folders. New CD burning software fixed it. D'oh!
