Installroot Patches

Installroot patches are small pieces of script that can be downloaded from the WWW for local execution. They are usually used to repair problems which hinder a Linux machine from booting.

To use an installroot patch, you must first boot off the installroot (CD or PXE). At the first installroot prompt, type p . You will then be prompted for a patch id. A list of current patches is given below, and an example of an installroot patch run is shown below.

The following installroot patches are available :-

This patch reinstalls and configures the Linux boot loader grub. Its most common use is to reinstall grub on a dual boot machine after Windows has just completed installation
