It appears Rufus is a Windows utility. Doesn't run on Linux. It also
seems to only make bootable USB flash drives, while I am burning to disk.
However, I think you found the issue of an efi bootable image on a
pre-efi computer. I guess the days of loading Linux on old computers are
past. I think the machine I am trying to use is probably around a 2003
vintage.
Thanks,
Michael

I assume that you have burned the iso to a disk? If so, I recommend using Rufus
to make the bootable iso. I use Balancia Etcher to make bootable usb drives. I
have found that other image burning software does not properly burn the ISO’s.
Rufus also has a nice drop down box to choose bios or efi bootable images. I
think you have made an efi bootable image for a computer that only supports
bios. Just my guess.

Okay, I didn't think about that. But the computer should at least boot to the
ISO, shouldn't it? I tried with a newer I5 Optiplex 745 (which, I believe, is
64 bit) and I can't get it to boot to the DVD either.

The Pentium 4 is a 32 bit CPU. CentOS 7 is 64 bit only. You need a Core2duo or
better CPU to run CentOS 7.
I’m sure someone will correct me if I’m wrong.

Trying to set up an old computer to play with Rivendell. It is an old
homebuilt Pentium 4 from long ago. I downloaded the Centos7 minimum install ISO
and burned it to a DVD. I also burned it to a USB stick. I can't get the
computer to boot to either one. I've set the boot order to DVD then HD and boot
from USB is enabled. The DVD drive flashes like it is reading, but it doesn't
boot. The screen blinks a bit, then tries to boot from the hard drive. I used
Brasero to burn the ISO to the DVD. It looks right as best as I can tell, but
it has been 10 years since I have done this.
Any suggestions on what I might be doing wrong? Maybe the hardware is too old
to boot to the new ISO?
Thanks.
