Hi, I installed Ubuntu first, then I installed Debian and Finally I installed Fedora. If I remember correctly Fedora's Grub did not include Debian in the list. Then, I tried to install Debian's Grub but it did not see Fedora. Finally, Grub from Ubuntu sees all OSes. But Grub seem's to be updated everytime the updates install a new kernel, and so, Ubuntu's Grub gets replaced by Debian's Grub and I can't choose to boot Fedora anymore. Is there a way I could go about this? Like, preventing Grub from being overwritten or something? Or a way to make sure all OSes appear in each of the Grubs?
