I have Lenovo T520 4243 series. I need to change the boot option in Bios settings, because first option is Lan and second is HDD but i would like to boot from DVD or Usb DVD.
My problem is i cannot edit the settings, also unable to set bios settings to default F9 is is not allowed.
In password menu i can just change or set Power-On Password User and Master. Supervisor password is not highlighted.
What can i do ?
