52.3.1 Fails to Load the GRUB Boot Loader
If the hardware is functioning properly, it is possible that the boot loader has become
corrupted and Linux cannot start on the machine. In this case, it is necessary to reinstall
the boot loader. To reinstall the boot loader, proceed as follows:
1 Insert the installation media into the drive.
2 Reboot the machine.
3 Select Installation from the boot menu.
4 Select a language.
5 Accept the license agreement.
6 In the Installation Mode screen, select Other and set the installation mode to
Repair Installed System.
7 Once in the YaST System Repair module, select Expert Tools then select Install
New Boot Loader.
8 Restore the original settings and reinstall the boot loader.
9 Leave YaST System Repair and reboot the system.
Other reasons for the machine not booting may be BIOS-related:
BIOS Settings
Check your BIOS for references to your hard drive. GRUB might simply not be
started if the hard drive itself cannot be found with the current BIOS settings.
BIOS Boot Order
Check whether your system's boot order includes the hard disk. If the hard disk
option was not enabled, your system might install properly, but fail to boot when
access to the hard disk is required.
