1README for mondo/mindi usage on UEFI based systems
2
3A new replacement of the BIOS has emerged called UEFI.
4
5Depending on the boot mode you use (UEFI or BIOS), mondo and mindi will have to behave accordingly.
6Depending of your choice, software configuration, you may also use GPT or MBR as a file table format. Refer to README.ia64 for more details on how mondo and mindi deal with that.

8If when booting in UEFI mode on a system, the current media made doesn't boot automatically, in order to restore your system, you'll have to go on the UEFI shell and do something like the following:
9
10Shell> FS0:
11FS0:\> CD EFI
12FS0:\EFI\> CD BOOT
13FS0:\EFI\BOOT\> grub
14
15This supposes that your drive is seen as first media (FS0), which can be confirmed using the map command at UEFI shell prompt. Search on the result line for CD related lines.
16
17Then you'll be at the standard boot menu to restore your system with the choice of options.
18You'll have to respect the case used in the example upper.
19
20For now, MondoRescue doesn't invoke efibootmgr to recreate menu entries, so you'll have to recreate them manually for now. Which also means that after the restore, during the next reboot, you may have to select on which device to boot as the menu may be worngly pointing to inexistant media. In some case the correct entry will automatically be added to your menu. If that's not the case, use efibootmgr from Linux to recreate it.
21We also do not support Secure Boot yet. So you'll have to boot the MondoRescue media with it disabled.
