<title>The EFI System Partition</title>
<para>This partition, also known as the <emphasis>ESP</emphasis>, is needed
when booting the system with UEFI. It stores the EFI application that is
ran during bootup. The boot drive can be partitioned with MBR Partition
Table, or DOS, but compatibility issues will tend to arise as a result.
Therefore, it is always a good idea in this case to partition the boot
drive with a GUID Partition Table (GPT). Typically 256 MB for this
partition suffices, although the needed size for a Grub EFI application can
go down to 20 MB or lower. The partition label should be 'EFI System' if
using <command>fdisk</command>.</para>
<para>For Grub, the EFI System Partion should be located at
