I would like to know more on this custom.cfg file you mention. Would I edit my grub.cfg file to my liking and save it as custom.cfg in the boot directory?
Then save the 41_custom file as 09_custom in the /etc/grub.d/ directory?
My suggested way will NOT give you ONLY 3 entries on the on-screen boot menu, since the grub.cfg entries will come after whatever is in custom.cfg. However, you will have your favourite custom entries right at the top.

Seems you responded just as I was typing a new comment. I did look at the contents of 41_custom and had a question.

Code: Select all

#!/bin/sh
cat <<EOF
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
EOF



Does this also get added to my custom.cfg file at the end?

No. The custom.cfg is a pretty clean file with just the boot entries you want. Don't change 41_custom and just let it do its thing.

Ok, so just run my usual sudo update-grub from terminal then? (I will monitor the output of what displays on the screen)

No update grub needed. Just edit the custom.cfg and reboot. That's it.

Perhaps post the custom.cfg you have created under /boot/grub/custom.cfg as text code-block.
This is to avoid any potential typos within that file, may stop to show the added entries,
and you might wonder what's going on.
E.g this way:
Open terminal as normal user and run:

Code: Select all

xclip -selection clipboard -i /boot/grub/custom.cfg
This would send the content of custom.cfg into the "clipboard".
Now within the editor of a reply post, click on [</>] code-block icon,
to get the code-block tags inserted - thos guys: [code][/code]
The cursor is now located between the code block tags.
Press Ctrl+v to paste the custom.cfg from the clipboard.

Just saw this post. I had updated grub and I'm close but no quite there.
Seems my custom.cfg entries were added to the end of my grub menu.

Hmme ... , I guessed it...
Please do not have anything else but only the menu entries within custom.cfg
Here the same reduced to menu entries only:

Code: Select all

Ah OK. That's how my custom.cfg started when I wrote it and I added the other sections from the grub.cfg file thinking I needed them.
Grub still confuses me compared to the LILO days. :rofl:

I'll edit the custom.cfg file back to what I originally had it. Do I still run update-grub afterwards?

Re: How do you edit the grub menu by hand?

No. No update grub needed. EVER. The custom.cfg file is just a list of grub entries. No scripting bits.

I mean, I gave you the whole contents of the custom.cfg for you to copy and paste quite a few posts ago.
