Interestingly, when I boot install USB drive, I randomly see SSD as sda or sdb, and HDD as sdb or sda....
https://bugzilla.opensuse.org/show_bug.cgi?id=1216070 Assignment of /dev/sd* has altered dramatically "resolved fixed" 3 months ago TW's kernel configuration has some differences from Leap's, beside incorporating new features. These can affect device enumeration, which affects device assignments.
...Anyway, regardless I place /boot/efi on beginning of SSD or 1st NVMe, BIOS has troubles to find boot openSUSE. Also, when I press F12 to manually select boot device, I sometimes get info that the firmware was reset (Problem with CMOS battery or so?), but otherwise everything seems correct there.
UEFI BIOS have a rather wide variety of behaviors that distinguish them from others. They are an art form. :p Be glad yours has an F12 menu that works. :)
When I install Leap with above setup, it works. I have similar setup (2x NVMe, 1st with /boot/efi and encrypted LVM with /and swap, and 2nd with encrypted / home) on another machine, and I use to use setup with /boot/efi and rest in encrypted LVM for years, so I'm sure this setup works reliably. So I wonder if I do something wrong or I face some issue with motherboard of my desktop...?
It's unlikely you are doing anything that is technically "wrong". Most reliable setup I have found is to install only one Gnu/Linux bootloader per PC. This includes having only one ESP filesystem, KISS technology. :) All except one of my UEFI PCs boot using TW's Grub-efi. The other UEFI (from which I type this, which has 5 openSUSE installations), and the older, all boot from openSUSE 13.1's (or older) Legacy Grub, some with upwards of 40 Linux installations, and only about 1 or so with less than 4. I try to avoid fixing what ain't broke. :) -- Evolution as taught in public schools is, like religion, based on faith, not based on science.
