Can't disable secure boot from the BIOS | Need Help !



I am having troubles with my bios because the secure boot is not showing up for me at all. I have looked everywhere but nothing at all.

I am using BIOS and not UEFI. I also have the acer aspire M5910 model. My BIOS is AMI (American Megatrends INC) 1985-2010.

    I don't work for Acer.  But let me give you an unofficial, approximate timeline for secure boot.


    Acer first started shipping desktop computers that had a UEFI that supported secure boot around August/September of 2012 when Windows 8 was released.


    From August 2012 to late 2013, desktop computers that came pre-installed with Windows 8 had a UEFI with secure boot capability and it was enabled.  Those same desktops that came pre-installed with Windows 7 most likely had a different UEFI with no secure boot capability during that same time period.


    Most any desktops that were shipped from late 2013 to present have secure boot capability (including desktops that came pre-installed with Windows 7----although it would have been disabled by default for Windows 7 computers since Windows 7 doesn't support secure boot).


    Your desktop computer seems older than August 2012 so I'm guessing it doesn't support secure boot.  And that's probably the reason that you can't find it----because it doesn't exist in your UEFI/BIOS.


    I'm not an Acer employee.
