To configure the GRUB2 bootloader on SUSE Linux, use the file /etc/grub2/grub.cfg. I can be generated by the command
grub2-mkconfig -o /boot/grub2/grub.cfg
from /etc/default/grub and the files in /etc/default/grub
/etc/grub.d/*____
\
--- (grub2-mkconfig -o /boot/grub2/grub.cfg ---> /etc/grub2/grub.cfg
/
/etc/default/grub
The best way to add a menu item to your grub2 boot menu is to add the command menuentry to the end of /etc/grub.d/40_custom like this:
- change /etc/grub.d/40_custom to look like:
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
menuentry linuxintro{
}
- call grub2-mkconfig:
# grub2-mkconfig -o /boot/grub2/grub.cfg Generating grub.cfg ... Found theme: /boot/grub2/themes/openSUSE/theme.txt Found linux image: /boot/vmlinuz-3.7.10-1.40-desktop Found initrd image: /boot/initrd-3.7.10-1.40-desktop Found linux image: /boot/vmlinuz-3.7.10-1.16-desktop Found initrd image: /boot/initrd-3.7.10-1.16-desktop No volume groups found error: syntax error.
- woops ;) Add a volume to the configuration in /etc/grub.d/40_custom:
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
menuentry linuxintro{
set hd=(hd0,0)
}
- and run mkconfig again:
# grub2-mkconfig -o /boot/grub2/grub.cfg
