[Swift SF315-41G] Can't change the Boot Mode from UEFI in my BIOS

Hi, I was trying to fix the No Bootable Device error on my Acer Swift SF315-41G laptop, and a recommended solution seemed to be changing the Boot Mode from UEFI to Legacy. I unfortunately can't do that though, because the option is greyed out and inaccessible in my BIOS. I tried to find a way to fix this, but all I found was setting a supervisor password, which didn't do anything. Seeing as I'm not great at tech and can't seem to find a solution to this all by myself, I'm hoping that you guys could help me.

I'm mainly looking to fix the Boot Mode issue, but If you have a different solution for the No Bootable Device error, definitely let me know. Thanks in advance for any help!

Hi,
Give this a try and see whether it fixes the problem:"No Bootable Device" Error Message - Acer Community

Those old 'how to' articles that talk about Legacy mode are really no use any longer. That was for Windows 7 and before... Everything since then has used UEFI instead, and the newer computers don't have drivers for W7 so don't even bother allowing the change.
