Cannot enable Legacy mode to install bios

Recommended Posts

Hello. I'm currently running windows 10 on bios version 1.00 and want to upgrade to 1.03 but cannot boot Ms dos flash in uefi. There is no option to enable Legacy mode and the option to disable uefi in bios is greed out. When I try booting from flash in bios, it shows black screen and returns back to bios screen. My rig is a p157sm. Any help will be appreciated as I'm looking to install prema bios mod.

Hi!

Try go in bios setup menu, and disable "Secure Boot" and "Fast Boot".

Secure boot disabled and grayed out. Uefi is enabled and grayed out no option for fastboot. This is why I'm confused.

In order to change the secure boot setting, you need to set a supervisor password.
Once password is set, secure boot setting will no longer be greyed out. Disable.
Switch UEFI to legacy and save. Now enter BIOS again and clear the supervisor password.

      i want to ask two favours and a question from this community ..
       
      1.) Can someone mod my 940 mx to increase the target temperature and allow higher overclocking than 135hzband voltage control
       
      2.) Allowing my i5 7200U to be undervolted to reduce overall heat 
       
      The question : I repasted my gpu and cpu cleaned it thoroughly, made sure twice everything is connected properly, use a cooling pad and yet the upper portion of my chasis above f1-f12 keys is so hot that i can roast peanuts on it. 
       
      (if i left out any info or missed something please reply i would really love to have a page that has everything for people who have this laptop specifically for light gaming.)
