default 0
The first menu entry title linux is the one to boot by default.
timeout 8
After eight seconds without any user input, GRUB automatically boots the default
entry. To deactivate automatic boot, delete the timeout line. If you set timeout
0, GRUB boots the default entry immediately.
The second and largest block lists the various bootable operating systems. The sections
for the individual operating systems are introduced by title.
• The first entry (title linux) is responsible for booting SUSE Linux Enterprise.
The kernel (vmlinuz) is located in the first logical partition (the boot partition)
of the first hard disk. Kernel parameters, such as the root partition and VGA mode,
are appended here. The root partition is specified according to the Linux naming
convention (/dev/hda7/), because this information is read by the kernel and
has nothing to do with GRUB. The initrd is also located in the first logical
partition of the first hard disk.
• The second entry is responsible for loading Windows. Windows is booted from the
first partition of the first hard disk (hd0,0). The command chainloader +1
causes GRUB to read and execute the first sector of the specified partition.
• The next entry enables booting from floppy disk without modifying the BIOS set-
tings.
• The boot option failsafe starts Linux with a selection of kernel parameters that
enables Linux to boot even on problematic systems.
The menu file can be changed whenever necessary. GRUB then uses the modified set-
tings during the next boot. Edit the file permanently using YaST or an editor of your
choice. Alternatively, make temporary changes interactively using the edit function of
GRUB. See Section "Editing Menu Entries during the Boot Procedure"
