Inspiron 15 3567, boot file not found, BIOS password locked
I have a problem when I start my dell laptop inspiron 15 (out of warranty on May 25, 2019) then an error comes on screen that boot device not found. And other problem is that a bios password is in my laptop. So I cannot solve the 1st error boot file not found because of password which is attached to my bios setup. All the methods of removing bios setup password did not work on my dell laptop. I am worried. Please give some solutions.
