Re: Adding configfile entry to grub.cfg

[Arbiel (gmx)]

Hi

Yes, you can add entries into your grub.cfg on the SSD.

The lines to add should read something like

menuentry 'boot from my USB key' {
configfile (usb0,msdos1)/boot/grub2/grub.cfg
}



1) 40_custom
This way, you also have to update grub

### BEGIN /etc/grub.d/40_custom ###
# 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.
### END /etc/grub.d/40_custom ###

2) 41_custom
If your grub.cfg file already contains these lines

### BEGIN /etc/grub.d/41_custom ###
if [ -f  ${config_directory}/custom.cfg ]; then
  source ${config_directory}/custom.cfg
elif [ -z "${config_directory}" -a -f  $prefix/custom.cfg ]; then
  source $prefix/custom.cfg;
fi
### END /etc/grub.d/41_custom ###

you only have to record the lines into the /boot/grub2/custom.cfg file.
