Samual and Steve, When I installed Fedora I got the screen where you
can turn UEFI off. Since I wanted to promote the DVD drive over hard disk boot, I turned
it off. I thought that was permanent. However, now I can no longer get to that screen.
I have managed several time to interupt the boot, but I only have the choice of the
existing Fedora or Rescue. Something, which has to be Fedora related, since it worked
before, is stopping me booting from the DVD.
You can boot a DVD or USB drive in EFI mode. That's what I use on all
the new laptops that I install. What laptop do you have? Did you try
the suggestions from my last email? Once you get to the GRUB menu, it's
too late. If you watch carefully at the bottom or top of the screen
when you first turn the laptop on or reboot it, there is often a very
brief message saying which key to use to get the boot menu or the BIOS
setup. The key for setup is usually F10 or DEL.
