Finally, after much work EFI (much thanks to the anaconda team and all those testers) support is quite mature in Fedora 16 Beta. There are still some issues (➫ bugzilla) but in general it's working.
Hardware: It's not easy to see if your hardware supports EFI booting, best is took in your BIOS and see if the magic EFI keyword appears somewhere.
Boot media: If you want to try out an EFI boot media you've got two or three common ways of doing so.
- First you try the Fedora 16 Beta DVD or netinst images.
You can write those images to a DVD using nautilus (right click on the iso ...).
Note: If you want to use them via a USB-stick you need to use the livecd-iso-to-disk tool, part of the livecd-tools package. Also remember to pass the --efi switch. In generall it should look somewhat like the following example:
- The other way is to use the efidisk.img which can be found in the images directory of the DVD images. This image can be written to a USB-stick using dd:
$ sudo dd if=efidisk.img of=/dev/sdg
$ sudo livecd-iso-to-disk --format --efi \ Fedora16-DVD.iso /dev/sdg
Also note that the LiveCD images are
/sys/firmware/efiexists on systems booted via EFI)
EFI plus some boot optimizations can then finally lead to quick boot process.
