 GRUB can also be used for network booting, but version 2.00-1 times out on large initramfs images (this makes PLD Rescue boot impossible).

+To set up kernel boot via EFI with no other boot loader:
+  * install your kernel and make sure you have a valid ''/boot/initrd'' for it
+  * install [[#efi-boot-update]]
+  * update /etc/efi-boot/update.d/kernel.conf so it contains proper 'root=' directive in $ARGS (required for Dracut-generated initrd)
+  * run [[#efi-boot-update]] (note, this will only work if already running via EFI)

 Instead of loading a boot loader and starting the operating system one may wish to enter the EFI shell. The EFI shell is often not
 included in the system firmware and must be installed separately. For convenience, PLD Linux provides the **efi-shell-{ia32,x64}** packages with pre-compiled EFI shell executables. These can be installed like a regular boot-loader – manually or with [[#efi-boot-update]]
