can’t boot linux, but can boot windows

Hi,

I am trying to install Fedora 12 using the installation DVD. When I boot the machine, I get an error message “No boot device available”. I get the same error when attempting to boot from other CDs and DVDs for various other versions of linux, but I can boot Windows XP using a windows install disk in the same DVD drive.

The machine is a Dell 670 workstation, containing one SATA hard disk. I have tried enabling and disabling the SCSI controller, but that has no effect. The machine previously had Windows XP installed, which I deleted using “killdisk”. I only want to install Fedora: I am not trying to set this up as a dual boot machine.

Any help would be great.
