[SOLVED] Laptop started not recognizing EFI boot partition in SSD

I have installed Arch on my SSD (Samsung EVO 860) with EFI partition (~950MB), as in Arch wiki, and used it successfully for a month or so. However, yesterday I swapped hard disks in Laptop (I inserted the old one - HDD 1TB (that came with my laptop) for certain purposes. I have swaped back to my SSD, however, it seems that EFI partition is not recognized anymore. There was once a BIOS message saying "check media cables", but I have found everything to be connected well. After that, I started getting "No bootable device" message. I have been tinkering with my BIOS settings afterwards, but the result still seems to be the same.

My BIOS settings currently:

I have tried turning off secure boot, with no difference made

These are what I get:

I have made a bootable Arch live USB in order to reinstall EFI parititon, buf after standard Arch live USB boot screen I get this output:

(But maybe this Arch USB not working is yet another issue not related to my original problem, since I have not tested this Arch USB on another computer)

I have checked my SSD partitions with gParted live USB, and everything seems to be in place (forgot to make a screenshot of it).

However, I am still trying to make boot from Arch USB working and reinstall EFI partition on my SSD.

The specifications of my laptop can be seen in my "signature" below.

I apologize for not doing more steps to solve this problem, although I am currently working on it, but I posted this thread in such a hurry since I kind of need my SSD working again soon.

I will provide with more information/output needed to solve the problem ad hoc, per your requests.

Unfortunate that you seem to be getting such an error on your Arch USB, FWIW you should be able to chroot from the gparted live disk and reinstall your EFI bootloader there. But yes it is quite likely that your UEFI decided to remove the entry of the unavailable disk, some try to be that "helpful"
