I just purchased my Nitro 5 AN515-43 with the intent of installing Linux as a dual boot, however, the BIOS does not allow the option to boot from CD or USB.  There is no option for Legacy boot.  I have updated to the latest BIOS version but that option is not provided.

    You do not need Legacy for that. Linux supports UEFI boot options.
    USB boot option would show up only if the Linux bootable USB is inserted.

    Just to clarify.  When I enter into my BIOS, these are the options that I have:
         Boot Mode      UEFI                   Nothing else
         Secure Boot    Enable/Disable
         Boot Priority:    
               1.  Windows Boot Manager


    There is no option to boot from CD/USB or to select Legacy (as I've seen in other posts)

    I looked at the other BIOS updates to possible select an earlier version but none indicate this as an issue and I am not permitted to install an earlier version of the BIOS.

    I have a dual boot on the same laptop, I understand that you are not happy with Acer hiding all the usefull options that are available in BIOS, like I am. You will be not told how to unhide them here nor by Acer support, so we have to live with it. Make a bootable linux flash drive with rufus for example and format it as GPT - non CSM, enable boot menu in BIOS => Advanced Options (you yave to put admin pass to do it) then reboot with the flash drive plugged in and then press F12 for the boot menu. You will be able to select the flash to boot from. Its really a shame that we don`t own our HW in the reality. You can select the hidden options with the help of the efi shell or grub (you will have to dump the BIOS first), but you have to know what you are doing.
    Please click "Yes" if I have answered your question.

    Thanks for the response.  After watching some YouTube videos, I gave it another try.  Apparently when I made my first ISO image, I did not create it properly and therefore it wasn't a good bootable USB.  After doing it again watching my steps, the ISO image was recognized as a bootable USB and everything worked well.  Since the BIOS didn't give the option, it confused me and I couldn't understand why it was not an option.

    Thanks again.  Problem solved and Linux is working well as a dual-boot environment.
