Official GRUB page
GNU GRUB is a boot loader. It was derived from GRUB, GRand Unified Bootloader, which was originally designed and implemented by Erich Stefan Boleyn.

Info
The master boot record (MBR) is a special area on your hard drive that is automatically loaded by your computer's BIOS, and is the earliest point at which the boot loader can take control of the boot process.

Starting Zeta from the GRUB bootmanager

You might want to use LILO or GRUB instead of Zeta's Bootman.

The following way of adding Zeta to GRUB's menu is done in Fedora and Red Hat 9 (on how to edit GRUB's menu in SUN Java Desktop System and SUSE read below).

When installing Linux with the Red Hat Installation Program (Anaconda) you will get a list of every bootable partition listed, including partitions used by Zeta and other operating systems. You can then in the 'Boot Loader Configuration' add Zeta to the boot loader. To change the operating system booted by default, select 'Default' by the desired operating system.

You can also add Zeta after having installed your chosen Linux distribution. Log in as root on your Linux system. From the Programs menu, go to Accessories and choose Text Editor.

In the Text Editor choose File and than Open. Go to /, than choose the boot folder and than the grub folder. In the grub folder choose the file grub.conf.

The grub.conf file should look something like this:

In the bottom of this list (configuration file) you can add the following information to make grub also boot Zeta:

> title Zeta
> rootnoverify (hd0,4)
> chainloader +1

(hd0,4) is relative to the partition that you have installed Zeta, in this example 4.

You can later easily change what operating system that should boot by default:

Advanced Boot Loader Configuration
If you for some reason decide to install Linux after having installed Zeta, you can choose to not install the Linux boot loader in the master boot record (MBR), but rather install it on the earliest point at which the boot loader can take control of the Linux boot process. Bootman will then take control first and let you choose between booting Zeta, Fedora / Red Hat (and Windows). Choosing Fedora / Red Hat in Bootman will then start GRUB or LILO, which then will boot up your Linux system.

If you choose to keep Bootman as your main boot loader, you will have to add your Linux system to it.

Changing the GRUB Bootloader in Sun Java Desktop System and SUSE
In Sun Java Desktop System and SUSE changing the GRUB's configuration is a bit different then under Red Hat and Fedora.

The easiest way us to log in as root on your Linux system. From the Programs menu, go to Accessories and choose Text Editor.

In the Text Editor choose File and than Open. Go to /, than choose the boot folder and than the grub folder. In the grub folder choose the file menu.lst

In the bottom of this list (configuration file) you can add the following information to make grub also boot Zeta:

> title Zeta
> rootnoverify (hd0,4)
> chainloader +1

(hd0,4) is relative to the partition that you have installed Zeta, in this example 4.
