Confused drives/User

[MOE-LARRY&CURLY]

Good day. After some difficulty I was able to get a live usb of MX Infinity going. I set up a persistence on the 64Gb said drive. This may have to be my fall back. I then did a custom install on the internal SSD (the HDD has failed on me).
Within the MX installer it read my SSD as sda and HDD as sdb. It has always been HDD on sda and SSD on sdb previously. I believe machine recognizes the bad HDD, Maybe. After install and reboot, was started in Grub. There were 2 options of both the AMD64 and AMD64 (sysvinit), 4 choices in all . I chose AMD64 knowing defaults with systemd. With the usb unplugged at restart , it booted fine into MX, as demo. I set up user on the live and did same in the installer. Now it see’s the drives differently as I mentioned and I just know this can be corrected but I’m not sure how. Wondering if there are smartctl options? The MX boot option UEFI manager has 6 entries. I tried installing the EFI stub, now just about as confused as the PC itself! I will include some screen shots with various info. I appreciate and advise words of wisdom! Thank you.

The order for naming drives as sda, sdb, etc is variable, it just depends on which drive is accessed first. It really doesn't matter at all. That nomenclature should not be used in /etc/fstab, because it's unreliable. Use a disk label or UUID instead.
