My friend bought Asus Vivobook E203-NAH with 500GB Hdd & Win10 pre-installed. It has UEFI bios.
She wants to change to Win7 because everything feels sluggish in Win10, compared to her previous Asus X201-E with Win7.
Researching the net, I always read 3 pre-requisites to install Win7 in a computer with UEFI bios :
1. Disable Secureboot
2. Disable Fastboot
3. Enable "Launch CSM" or "Compatibility Support Module" , or enable "Legacy Mode" in Bios.
Problem is, I can only find settings for Secureboot & Fastboot, but there is nothing about Legacy mode, or Launch CSM in the bios. Does it mean it is impossible to install Win7 in this laptop ?
Is "Enabling Launch CSM" or "Legacy Mode" really required to install Win7 ?
I provide the bios screenshots here for reference.
