Hi, About this documentation [0], finally talks about rescue a bootloader with live images ... (but I will wrote about that in another time) I run in trouble on cloning a disk from an old computer and starting booting on a new computer , security get the thing more complicated, I had to disable secure boot and selinux not sure , but I advice boot with kernel parameter selinux=0 my old computer was bios legacy and the new have UEFI and here starts the challenge . I think just after do the lvm steps (my disks have lvm partitons) [1] I start to boot correctly and the problem (I think) was that I need to run one time 'grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg' . I think is wrong use grub2-mkconfig -o /boot/grub2/grub.cfg , like it is wrote on grub2 on a uefi system [2], should we fix it ? and the advice of boot with selinux=0 ?
