Hi,
I need decided for Endeavour for my homework vm and the installer doesn’t want to accept my partitioning. I need at least the root part encrypted. I also have issues with the network, so I have to do the offline instalation.
If the VM is UEFI enabled you need to create fat32 flag = boot and mounted as /boot/efi but if it is legacy Bios (MBR) you do not need the ESP EFI fat32 partition at all…
