  • Regarding os-prober see this answer, that's not an error but a warning. There is a problem with /etc/default/grub or a file in /etc/grub.d/. Please add the output of cat /etc/default/grub via edit to your question. Did you edit any file in /etc/grub.d/? If so, post the contents of that file too, please. Take a look at /boot/grub/grub.cfg.new at line 267 to check which file in /etc/grub.d/ produces the error. – mook765 Jun 16 '23 at 19:08

os-prober has been disabled, you have to edit /etc/default/grub to add: GRUB_DISABLE_OS_PROBER=false and run sudo update-grub
