If you chose to install GRUB on each Ubuntu installation, then you&#39;ll have to use Grub Customizer on the most recent installation. If not, Grub Customizer needs to run on the Ubuntu that installed Grub.Logixhttps://www.blogger.com/profile/03026963810377267607noreply@blogger.comtag:blogger.com,1999:blog-852161773840707483.post-75952146093966828972019-01-29T02:32:11.202+00:002019-01-29T02:32:11.202+00:00If I have 2 or more ubuntu installations, which is the one I have to install grub-customizer on ? What exactly determines that ? E.g. I have ubuntu and lubuntu on my system. The default (top) choice has so far been ubuntu. I successfully installed grub-customizer on the Ubuntu partion and it works. But could I have chosen the lubuntu partion, installed grub-customizer there and modify the grub menu ? Would that have worked ? And if not, then why ?<br /><br />Of course I doubt that it would have worked. My hunch is that the grub.cfg file that counts is the one on the partition that booted by default all along (i.e.Ubuntu in my case). But what If I use grub-customizer to change the default OS to lubuntu, would grub now read the grub.cfg in the Lubuntu partition ? If so, would I then have to install grub-customizer on lubuntu because THAT is the default OS now ?Anonymousnoreply@blogger.com
