Removing Red Hat Linux
A Removing Red Hat Linux
To uninstall Red Hat Linux from your system, you will need to remove the LILO information from
your master boot record (MBR).
There are several ways to remove LILO from the MBR of your machine. If you are running Red Hat
Linux, you can replace the MBR with an earlier saved version of the MBR using the /sbin/lilo
command:
/sbin/lilo -u
In DOS, NT, and Windows 95 you can use fdisk to create a new MBR with the "undocumented" flag
/mbr. This will ONLY rewrite the MBR to boot the primary DOS partition. The command should
look like the following:
fdisk /mbr
If you need to remove Linux from a hard drive, and have attempted to do this with the default DOS
fdisk, you will experience the "Partitions exist but they do not exist" problem. The best way to remove
non-DOS partitions is with a tool that understands partitions other than DOS.
You can do this with the installation floppy by typing linux expert (without the quotes) at the
boot: prompt:
boot: linux expert

fdisk, type
