Hi!
My grub don't set the 'vmlinux / initrd.img / menu-entries' parameters anymore when I run
in Terminal:
sudo update-grub
How can I fix that?
What changes did you make to your system?
However there are some options available. If you are able to boot the system you are having issues with the method from help.ubuntu.com will be helpful.
The most relevant part if that is the case is:
sudo grub-install /dev/sdX # Example: sudo grub-install /dev/sda
then run sudo grub-update
Also from help.ubuntu.com is boot-repair
It is also available in a rescue disk format boot-repair-disk
Good luck
Got it,
recovered my older files in "/etc/grub.d" and edited it with Grub_Editor.
(SOLVED)
Great news. Glad you were able to resolve it.
