<p class="MsoNormal"><span lang="EN-GB">I am pretty sure this depends on how the installation was started. That means you will have to boot your FAI installation using UEFI as well. This can be a bit tricky if you want to install from network - I also tried
setting up PXE with UEFI some time ago and failed.<br>

<p class="MsoNormal">I am pretty sure it is not possible to set up grub-efi correctly when booted in legacy mode. While it is possible to detect that we are actually running an EFI-capable machine (dmidecode or lshw can detect that), we cannot access the efi
variables under /sys/efi since the firmware doesn't expose them to the host when running under CSM aka "Legacy mode".<br>
<br>
Booting from USB with UEFI is possible, in fact I have such a USB device here somewhere. But I need to remember what I did, it was not (yet) completed in FAI at that time. I remember I wanted to make some patches available, but never found the time. This is
almost a year ago now. What you basically need is a small FAT partition preferrably of type 'ef' (EFI Boot Partition) on the USB drive, which contains a grub efi image as EFI/BOOT/BOOTX64.EFI. That image can be created with grub-mkimage and needs to include
at least all modules for reading the "main" partition and the grub.cfg on it. That will be mostly ext filesystem and msdos partition table, I think. That image should also include an embedded config file with a one-liner like<br>
configfile (hd0,msdos1)<br>
if the main partition is the second on the USB drive.<br>
<br>
I will try to find this again and post it here.<br>
