got bored and used the Terminal to see if my desktop PC's are UEFI or BIOS.

The command is actually:

Code:

ls /sys/firmware/efi/

Still same result:
No such file or directory.

More than likely you have - BIOS -- not UEFI hense it cannot find a efi folder

The laptop boots in LEGACY BIOS mode, yes, but it is UEFI. I've seen the UEFI bios console a couple of times.  In the inxi output reads:

Code:

UEFI [Legacy]: Insyde v: F.34

And

Insyde Software is leading worldwide provider of UEFI firmware

https://www.insyde.com/ When this laptop had W10 and a HDD I formatted to install W7 for it previous owner, who gave it to me as a payment for a job few months back. And I had a hard time because I didn't know it was UEFI,  it was the first time I dealt with that and had to read a bit and learn how to; enabling legacy mode in the settings, thus it could boot from the USB and install W7. So yes, it is UEFI. Like I said before, if I understand correctly, running

Code:

ls /sys/firmware/efi/

or

Code:

sudo efibootmgr

only tells whether your current Operating system is booting in UEFI or LEGACY mode not if the machine, the motherboard, the chip has a LEGACY or UEFI firmware which are two whole different things.

Also, running

Code:

sudo dmidecode -t bios -q | grep UEFI

Gives

Code:

UEFI is supported

So again, yes, looks like indeed, it is UEFI.
