2 years ago I try to install a Linux distribution.
- To do so I need to disable the secure boot and set the supervisor password.
- My keyboard was giving me problems at that time and now i don't know the password.
- I need it in order to change the boot options.
- I tried everything to remove the password.
a. I quit the battery, short the jumpers, it doesn't give a code to disable the password.
b. the last thing I did was to edit the bios update so i can remove that but i have the last update installed, now i can't do a downgrade and this file when i run it, it reset the changes that I made.
can someone help me.
