-It is possible to install Slackware to a disk that uses a GUID Partition Table (GPT), even on a machine that uses BIOS (i.e. you do not need a UEFI-based machine). Using GPT allows you to install Slackware onto very large disk drives (the theoretical maximum addressable disk size is 2 ZiB). As always, partitioning should be done prior to starting the 'install' script, however you must use a GPT aware partitioning tool, e.g. gdisk, cgdisk or parted (all of which are included with Slackware). The main sections below explain how to setup various popular boot loaders. +It is possible to install Slackware to a disk that uses a GUID Partition Table (GPT), even on a machine that uses BIOS (i.e. you do not need a UEFI-based machine).

-Skip the bootloader (LILO) section during install (LILO works but as of Slackware 14.1, liloconfig won't detect GPT partitions)After installation is complete, [[#Accessing the Slackware install, prior to bootloader installation|enter your local Slackware install]]. From here, customize /etc/lilo.conf_example and save it as /etc/lilo.conf. You will need to set LILO to install to the protective MBR of your primary disk and add entries for your chosen kernel(s) at a minimum, in addition to any other changes you see fit. Once you have done this, issue the 'lilo' command.+LILO should be configured by the installer and just workHowever some people have reported issues with liloconfig not detecting GPT partitions. If you encounter this issue skip automatic LILO configuration.

-<note warning>Whilst LILO works well with any file system format that is compatible with the FIBMAP ioctl (required to map files to block numbers), you //may// therefore have issues with XFS or Btrfs.

-If you want to use Grub 2, make sure you have a 'BIOS boot partition' (partition type EF02 in gdisk or cgdisk) somewhere on disk (at the start seems sensible). It should be at least 1MiB. Skip the bootloader (LILO) section during install. After installation is complete, [[#Accessing the Slackware install, prior to bootloader installation|enter your local Slackware install]].
