    Hi, I just getting same problem but after Window 10 it is working normal. But yes. if you want to getting this kind of problem then you should only install window 10 and if your pen-drive will be having window 10 setup only then it will shows in bios.

    Hi guys I also have the same problem. I went as far as taking out the laptop hard drive, my laptop is Acer Aspire 3 by the way. So I took out the lap top hard drive and formatted it clean, out of frustration, now when I put in my usb which is a bootable, thanks to Rufus, the laptop still doesn't detect the usb. I enabled F12 and found nothing but secure Boot which is Enabled and Boot priority order which is empty. Please help.

    In the BIOS menu, after <SECURE BOOT: DISABLE>

    go back to SECURITY, down is option <Select an UEFI file as trusted for executing:..>

    in this menu is possible to choose one or more UEFI files from connected USB drive and adding that to database (saved at TMP chip)

    After that and restart you can see your USB drive in the <F12 boot menu>

    well I contacted acer support.. they say a315 doesn't support windows 7 and legasy bios. 

    why these OEMs are forcing windows 10. we should make the choice, not them. perhaps this is my last acer laptop. 

    if anyone find any fix/hack pls let me know.


    thanks a l

    I've now gotten the USB option and it boots, however ...

    performed the steps of entering a password into BIOS, then using RUFUS under win 10 to create the bootable USB drive for Linux Mint 19.2 cinnamon, 64 bit

    after telling IOS to boot from USB, because the now have the option, it shows 4 options for the USB, Linux Mint 19.2 and COMPATIBILITY for LM 19.2

    the others are for testing purposes

    when I attempt the forst option, nothing shows up

    when I select the compatibility option, it boots to the LM cinnomon GUI.  But, the mouse and keyboard don't do anything, so it's unuable

    any suggestions?

    Hi Aryan, please follow the thread up. Clearly given out there.

    P.S. setting your password in BIOS is MANDATORY to boot your WINDOWS OS because it disable secure boot.
