Linux Mint gets the most complaints about Grub not updating but it is not really a Mint problem. The volume of complaints is due to the fact Mint is the most popular flavor of Linux.<\/p>\n\n\n

The other reason is so many people install Linux on older hardware. This is another example of why Agile is not now, nor will it ever be Software Engineering<\/strong>. Your Jenkins automated testing doesn’t test squat.<\/p>\n\n\n\n

Here is the real problem<\/h2>\n\n\n\n

Sorry about the phone camera flash. You can still see what is important. It is that 1 MiB BIOS Boot partition. I originally installed Mint on this 1TB SSD when it was in a really old AMD 6-core computer. Like the computer moved the drive to, it can, but it does not default to EFI boot. One has to change the BIOS settings. When I replaced the battery on the Mobo, that was one of the settings I missed changing back.<\/p>\n\n\n\n

You see, Mint (and probably most other Linux distros) the hardware wants a standard DOS boot. So, that 1 MiB BIOS Boot partition gets created with just enough code to launch the EFI partition. The typical end user thinks the machine booked from UEFI because that’s what it looks<\/em> like.<\/p>\n\n\n\n

Grub no like it<\/h2>\n\n\n\n

The Grub update process is poorly tested. Yes, I’ve given you Grub hacks before<\/a>, but this isn’t a Grub hack. If you are dual booting Windows XP or some other gotta have a DOS boot OS, all you can do is file a bug report. The Grub update process that runs as part of the graphical software update looks at the BIOS Boot partition expecting UEFI and can’t figure it out.<\/p>\n\n\n\n

Adding insult to injury, if you open a command line and do a <\/p>\n\n\n\n
