I installed on a BIOS-only system but migrated the disk to a UEFI+BIOS machine. I could switch to UEFI but I'd have to reinstall.

Okay I entered that command line as instructed and this is what was displayed;

total 0
drwxr-xr-x 6 root root 0 Nov 15 22:52 .
dr-xr-xr-x 12 root root 0 Nov 15 22:39 ..
drwxr-xr-x 7 root root 0 Nov 15 22:39 acpi
drwxr-xr-x 3 root root 0 Nov 15 22:39 dmi
drwxr-xr-x 4 root root 0 Nov 15 22:39 efi
drwxr-xr-x 17 root root 0 Nov 15 22:52 memmap

Not a techie so cant interpret what it means

Hope it helps though

      Thanks for posting. As it says above
      "If you see a folder named "efi", your system is booted into EFI mode."

          Bios only.
          I only used efi on win 10 never ever.

            Just to be clear, we're looking for the information your system supports, regardless of the OS. A system that supports UEFI may be booted into BIOS, but it still supports UEFI.

                You're welcome, note to self, must read the posts more clearly in future

                  TraceyC If you can choose between "Legacy" (aka BIOS) and UEFI, your firmware is UEFI. (Note: you should be using UEFI when installing the OS on your system if its supported).

                  I can install solus in 'uefi and legacy' and it always knows what to do which is uefi. so I don't need the UEFI only for solus in my rig. In fact when I force test distros next to solus in 'uefi only' they will still ignore installing a bootloader and will still sneak a grub .img boot with no /efi addition.
                  Mine is older so I never thought these three settings were actually enforced much at all by the underneath system (bios/uefi)

                    TraceyC Maybe it's helpful to add the poll tag to your thread to get more attention.

                      My system supports uefi and bios mode.

                      Win 10 is on uefi and solus bios only.
                      Win always destroyed my linux distros.

                        brent The last time right? before you get into trouble..lol

                            Axios I'm going to wait a few more minutes then start double-clicking them all😉

                              OMG Tracey you can't just ask what's in someone's boot loader 🫢

                              I didn't want to do the poll since I have Solus installed on so many devices. Every device that it was possible on is an EFI install. About half or maybe a smidge more (that's a technical measurement) the hardware will support a legacy install as well. I think only one (old laptop) is legacy only.

                              Let's keep this discussion on topic. If you have a question about your system, or a comment that isn't about the poll, please start a new thread.

                              Can do either, but prefer UEFI. Also use rEFInd to point to GRUB on each of my separate OS drives for booting.
