hi
i have a seriously problem
i went go to bios of acer laptop model : Aspire E15 , then first step set a supervisor password for example : *** and second step , change legacy mode to UEFI mode and finally step , Exit and save change
after reset , i receive this messege : -->> No Bootable Device . then i decided that again change UEFI mode to legacy mode but i can't do this because secure boot is Enable and i can't disable it because it option is deactive
also supervisor password is deactive and i can't change to Unset but i remember my password but i can't Unset because it option in deactive
What should I do for this problems ?thank you for help
