I tried installing DeBodhi on my desktop computer last night, triple booting with Mint and neon. On my 5th attempt I succeeded... Only to find that my computer now just boots into DeBodhi. To boot into either mint or neon, I have to hit f12 at boot and select the KDE Neon selection (one of six options, four of which do not work); I can select either Mint or neon from the Neon menu which comes up.

All I can think is that it created a second boot in a different location from where the first one was. I cannot get them to recognize each other.

I suppose terminal command [sudo update-grub] does not fix it?

I have a note from a Debian trouble shoot guide, not sure which release but it helped me:
Issue: Grub only shows Debian
/etc/default/grub
change
[# GRUB_DISABLE_OS_PROBER=false]
to
[GRUB_DISABLE_OS_PROBER=false]
sudo update-grub
Ie make that row active by omitting the #. No idea if this is related to your problem, I believe you can search and find the Debian post installation gudie I refer to.

@hehemrin I will check on that, Henrik. Thanks for the tip.
