Comment 167 for bug 1842320

Sorry,my mistake,I have two ubuntu installations. The first one runs kinetic,the second one jammy. I see the error on both the installations,but kinetic is able to ignore it,jammy can't. I gave a look at the link that you have provided,but the solutions proposed aren't detailed. It's not explained well what should I do technically to fix the error. Sorry If I'm a newbie and that's because I'm looking for the easiest method. For example,is there an alternative to grub to boot jammy ? Maybe if I install rEFIt,will it be able to boot my jammy ? thanks.
