Making an Ubuntu installation disc UEFI bootable
- by skytreader
I'm trying to install Ubuntu 12.04 on a machine with UEFI (Windows 8). Following Rod Books, I managed to get my system to boot using rEFInd. However rEFInd does not offer me any options to boot from my Ubuntu installer disc.
Another thing...after following Rod Books' instructions, my machine greeted me with something along the lines of "The bootloader is not trusted" (my usage of the term "bootloader" is possibly wrong; I'm not well-acquainted with these terms) I got to work around this by setting up some passwords in the BIOS and putting the renamed .efi of rEFInd to the trusted list. While in this screen, it showed me the drives with a possible .efi (among them, the drive S in Rod Books' guide) and one of the drives it showed was my optical drive with an Ubuntu installer. I tried browsing for an .efi in the Ubuntu installer but found none. True enough, at Windows, I searched the drive for an .efi but found none.
So how do I make my Ubuntu installer UEFI bootable?
