-Install master boot record (MBR) with integrated boot manager, providing a
-simple selection for specifying the device for booting from. This options is
-available only when using the default MBR and won't work if using the
---syslinux-mbr option.
+Install master boot record (MBR) with integrated boot menu: interactively choose
+the partition to boot from, with a timeout to load the default partition, or
+boot from floppy. When NOT using the --mbr-menu option a MBR with LBA and large
+disc support but without an integrated boot menu is installed (so it's not
+visible at all but instead directly jumps to the bootloader - being grub or
+syslinux). Note: This options is available only when using the default MBR and
+won't have any effect if you're using the --syslinux-mbr option.
