21.4 Uninstalling the Linux Boot
YaST can be used to uninstall the Linux boot loader and restore the MBR to the state
it had prior to the installation of Linux. During the installation, YaST automatically
creates a backup copy of the original MBR and restores it on request.
To uninstall GRUB, start the YaST boot loader module (System → Boot Loader Confi-
guration). In the first dialog, select Reset → Restore MBR of Hard Disk and exit the
dialog with Finish.

21.5 Creating Boot CDs

If problems occur booting your system using a boot manager or if the boot manager
cannot be installed on the MBR of your hard disk or a floppy disk, it is also possible
to create a bootable CD with all the necessary start-up files for Linux. This requires a
CD writer installed in your system.
Creating a bootable CD-ROM with GRUB merely requires a special form of stage2
called stage2_eltorito and, optionally, a customized menu.lst. The classic
files stage1 and stage2 are not required.
