How to diagnose suddenly failing grub boot from iso?
I have had my Ubuntu 18.04 system set up to optionally boot off several .iso files (on a different hard drive from /) and it's been working for a long time. I set it up using instructions on the Ubuntu wiki here. It worked well, I make Clonezilla backups, etc using this feature.
Recently, though, I tried to make a Clonezilla backup and the .iso wouldn't boot. I got an error message saying that it couldn't find the .iso. I checked and the .iso is still there in the same old spot. Testing showed that none of the .isos will boot any more.
I have made no hardware changes nor have I moved any of the .iso files.
I know there have been 2 updates to grub so far this year.
What is the suggested procedure for troubleshooting this problem? Since I didn't (knowingly at least) change anything, I am at a loss as to where to start. I compared the scripts in /etc/grub.d with the ones from a clean install, and I saw only the changes I had made. Did the updates to grub remove this functionality?
