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 te 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 D is seen as first media, which can be confirmed using the map command at UEFI shell prompt.
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.
21We also do not support Secure Boot yet. So you'll have to boot the MondoRescue media with it disabled.
