Introduction

You have installed a Linux installation but in its installation process you have chosen not to install grub, because among other things you did not want to alter the MBR. What happens right now? Your Linux does not boot. Probably you have tried to boot your Linux with "Boot Linux Indirectly" options and it does not boot. Maybe you have tried to reinstall grub with SGD and it fails with error 15 "File not found." 'What am I going to do', you ask yourself. Here are some answers.

Boot your system

In order to boot your system you need to boot it. How are you going to boot it if you do not have grub? You can just use SGD's grub for it from the SGD device you boot from. Select these menu items on the successive menus:

• Choose Language & Help
• English Super Grub Disk
• Linux
• Linux (Advanced)

In older versions you will see this menu:

• Boot Linux
• Boot Linux Directly

Choose Boot Linux Directly.

In newer versions you will see this menu:

• Boot Linux
• Boot Linux InDirectly

Choose Boot Linux

Choose your Linux's partition and boot it.

Install own distribution's grub.

Run as root from a terminal:

Debian, Ubuntu,...

apt-get install grub
update-grub

Fedora, Redhat,...

yum -y install grub
# Does any know what's the fedora's update-grub equivalent? Please comment in the forum.

Gentoo

emerge
# Does any know what's the gentoo's update-grub equivalent? Please comment in the forum.

The SGD way

Alternatively to install own distribution's grub you can install SGD's own grub on your distribution if you want to. If you want more information please ask it in the SGD forum and I will update this section.

Final thoughts

There are other ways of installing Grub such as using your Linux distributions install disk and issuing some rescue options but they are not funny so I do not comment them here. But anyone can write them here if (s)he wants to.
