Situation
After applying a kernel patch,
the system fails to boot with a GRUB ERROR:
Error 15: File not
found
Resolution
This problem is caused by an
incorrect change to the boot loader configuration file /boot/grub/menu.lst file
which can be corrected as follows.
Boot into the installed system
Boot the installed system as described in https://www.novell.com/coolsolutions/feature/19263.htmlstep #7, or as follows:
Edit/boot/grub/menu.lst
Make the following changes to /boot/grub/menu.lst:

Ensure that the changed file is saved as /boot/grub/menu.lst.
Test fix
Reboot the system and check that it now boots correctly. If the system does not boot correctly (e.g. due to an incorrect drive and partition setting in the root line), the "boot installed system" procedure described above can be used again to fix things.
Prevention
The boot failure can be prevented by editing the menu.lst file as described above after applying the kernel patch but before rebooting the machine.
Boot into the installed system
Boot the installed system as described in https://www.novell.com/coolsolutions/feature/19263.htmlstep #7, or as follows:
- Reboot the machine, press the
Escape key
at the grub boot loader screen. This allows for the boot options to be edited: - Confirm "OK"
- Select boot option "SUSE Linux Enterprise Server 10 SP1 - 2.6.16.53-0.16"
- Select 'e' to edit the boot options
- Select the root line " root(/dev/evms/sda1)"
- Backspace to "root("
- Change the line to be the correct boot device and partition. example: "root(hd0,0)"
- Press the
key to accept changes, Press "b" to boot the system.
Edit/boot/grub/menu.lst
Make the following changes to /boot/grub/menu.lst:
