I had not noticed that a Mageia 4 GRUB2 update in my daughter's desktop had erased the entry for PicarOS.
When Eimi mentioned PicarOS yesterday, I remembered I had not seen the entry in quite a while, so I tried to fix the problem.
Oddly, neither GRUB customizer nor the Mageia GRUB2 installer could fix the problem.
I thus tried the GRUB2 tool that is included in KDE. Fortunately, in a matter of three clicks, KDE reinstalled the PicarOS GRUB2 to the distro's partition. After that, I ran GRUB customizer and it added the missing entry.
I cannot describe Eimi's happiness when the computer booted to PicarOS once again. She played a lot with GCompris and drew many pictures.
PicarOS is a child's magnet without any doubt. The comfort with which my little daughter uses the computer when booted to that OS is truly notorious...
Interesting...I always add it manually. BTW, obsoleteman (a Pisi developer) gave me this method:
ResponderEliminarOn Konsole, as root, run os-prober command. If it does not see PicarOS, then go to pan B (add it manually) :P
