Hello, I've just burned FC3 iso1 (x86) onto a CD_RW (having first checked the md5 sums of the isos), and attempted to boot. It won't boot from the CD-ROM drive (I turned off all other devices to make sure, and got "Operating system not found".) Suspecting the burning process, I tried booting of a previous RedHat CD - same result. So it appears to be some kind of hardware problem. I installed FC1 and FC2 from this same drive, so it ought to work. The CDROM drive is enabled for booting in the BIOS (apparently - it's a Phoenix BIOS). Is there anything else I need to do, or are there any diagnostics that I can run? If not, is there another way of installing? (I only burned iso 1, intending to access the other iso images from my /home partition, which is what I did for FC2) -- Colin Paul Adams Preston Lancashire
