A few weeks back I noticed that my desktop workstation was no longer booting directly into the login screen for Ubuntu MATE 22.04, but straight to the BIOS/UEFI.
From the BIOS screen I can hit the F1 key, select the "Boot" menu and from there select which OS to boot into (but, of course, I shouldn't have to do that).
I have 22.04 on an internal nvme drive, 20.04 on a 2nd internal nvme drive, and a backup 20.04 on an internal SSD. I do not use Microsoft Windows.
I can access the GRUB menu by pressing ESC, and choose which OS to boot to from there, but I suspect some recent software update (or perhaps kernel update) caused this change.
Any tips on where I should begin to troubleshoot? And has this happened to anyone else? Thanks.
