 Bootloader
 ~~~~~~~~~~
 
-The default ZFS disk partitioning scheme does not use the first 2048
-sectors. This gives enough room to install a GRUB boot partition. The
-{pve} installer automatically allocates that space, and installs the
-GRUB boot loader there. If you use a redundant RAID setup, it installs
-the boot loader on all disk required for booting. So you can boot
-even if some disks fail.
-
-NOTE: It is not possible to use ZFS as root file system with UEFI
-boot.
+Depending on whether the system is booted in EFI or legacy BIOS mode the
+{pve} installer sets up either `grub` or `systemd-boot` as main bootloader.
+See the chapter on xref:sysboot[{pve} host bootladers] for details.
