extlinux - install the SYSLINUX bootloader on a ext2/ext3 filesystem
extlinux [options] directory
EXTLINUX is a new syslinux derivative, which boots from a Linux ext2/ext3 filesystem. It works the same way as SYSLINUX, with a few slight
modifications. It is intended to simplify first-time installation of Linux, and for creation of rescue and other special-purpose boot
The installer is designed to be run on a mounted directory. For example, if you have an ext2 or ext3 usb key mounted on /mnt, you can run
the following command:
extlinux --install /mnt
Force the number of heads.
Install over the current bootsector.
Clear the boot-once command.
Execute a command once upon boot.
Set the label to select as default on the next boot
Fall back to the next device on boot failure.
Reset auxiliary data.
Force the number of sectors per track.
Updates a previous EXTLINUX installation.
Force zipdrive geometry (-H 64 -S 32).
The extlinux configuration file needs to be named extlinux.conf and needs to be stored in the extlinux installation directory. For more
information about the contents of extlinux.conf, see syslinux(1) manpage, section files.
I would appreciate hearing of any problems you have with SYSLINUX. I would also like to hear from you if you have successfully used SYS-
LINUX, especially if you are using it for a distribution.
If you are reporting problems, please include all possible information about your system and your BIOS; the vast majority of all problems
reported turn out to be BIOS or hardware bugs, and I need as much information as possible in order to diagnose the problems.
There is a mailing list for discussion among SYSLINUX users and for announcements of new and test versions. To join, send a message to
