command for linux-generic fails when only other kernels available

Bug Description

Boot-repair failed for me (resulted in loading to grub prompt) because it told me to enter a command with "linux-generic" as the kernel. My system has no linux-generic installed. It only has linux-lowlatency. When I ran the repair again and changed that command, it succeeded.

Ideally, the program should see what kernels are available and make sure not to specify one that isn't there.

I should add that the command seemed to work, and everything said it was fine until the final end that said there were errors but I could try to reboot anyway. I think that it said there were errors when I used the linux-lowlatency substitute also, except then I booted successfully. So, I had to reboot a couple times and redo the whole process before I determined this problem and solution.

hi Aaron, thx for the report and sorry for the late answer.
Which OS did you try to repair ?

At the time, I was either running KXStudio 14.04 which is just a derivative of Ubuntu or was running KDE Neon (which I use now). Either way, it's basically plain Ubuntu on the kernel level. I had simply installed the low-latency variant and removed the generic. That was probably something I did and not default for those systems.

Of course, if the UI had simply provided the correct commands, then boot-repair would have worked without any confusion, even in my circumstance.

In other words: you can reproduce by installing plain Ubuntu, install low-latency kernel, remove generic, (and I suppose purposely mess up GRUB to really be at the same experience).
