Re: How To Disable Ubuntu OS Probing and GRUB (multiboot)?
I may or may not understand what you are asking .....
If the Fedora os-prober is working as you need, and Ubuntu's is not, then why not reinstall grub-pc from Fedora, and delete grub-pc and os-prober from each Ubuntu? I see no reason why this should interfere with Ubuntu updates, if you have removed grub-pc and os-prober from the Ubuntu OS's.
