.Changing a failed bootable device when using systemd-boot .Changing a failed bootable device
Depending on how {pve} was installed it is either using `grub` or `systemd-boot`
as bootloader (see xref:sysboot[Host Bootloader]).
The first steps of copying the partition table, reissuing GUIDs and replacing
the ZFS partition are the same. To make the system bootable from the new disk,
different steps are needed which depend on the bootloader in use.
