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

secure boot is deactive.JPGsupervisor password is deactive.JPG

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 ?

    Hi,

    Did you set User Password as well? What happens when you try to enter BIOS settings? It seems that you haven't cleared the Password.

    yes , i entered user password very well : *** and is okey

     

    when i try to enter Bios with press F2 key , the bios ask me Enter Current Password:  and i too enter ***password then bios settings open and everything okey but all options in bios is grey ( Deactive ) , Except two options that is Set User Password and Set HDD0 Passwordwhen i try enter bios setting.jpg

     

    i very amazing that why Supervisor password is grey ( Deactive ) !!!!!!!!!!!!!!!!!!!    ???????

     

    this is a software bug for acer ?? i before set a supervisor password then why now all option is grey ????

     

    i can't clear password , this is similar Deep Freeze software on OS , Perhaps Because the Secure boot option is Enabled and locked ( grey )

     

    help me

    Hi,

    You don't need to create a User Password, you only have to create a temporary PW for Supervisor, try clear the User PW.

    In BIOS settings, click User Password, enter the current PW and press enter, next leave blank for new PW and enter, confirm new password leave blank and enter.
