Operating systems generally do not offer the capability to uninstall themselves. If for any reason you want to uninstall Mandrakelinux, you can do so.
The process of uninstalling Mandrakelinux is done in two steps:
Delete all partitions related to Mandrakelinux on your hard drive (usually partitions hosting ext3 file systems and the Swap partition) and –– optionally –– replace them by a single FAT partition using DiskDrake (the section called “DiskDrake: Managing your Hard Drive Partitions”).
Remove the boot loader, LILO in this example, from the Master Boot Record (MBR). To do so, execute lilo -U in a console, as root.
If you have another boot loader, please refer to its documentation to determine how to regenerate the master boot record.
