ASUS Vivobook X413JA: Need legacy/CSM seems im stuck in UEFI

[dejag]

hi i recently bought a cheap and new laptop, ASUS Vivobook X413JA preinstalled with Windows 10. I can't seem to install Windows 7 I tried USB boot multiple times and installing it thru my w10 system basically running w7setup.exe but always error it wont install, and with usb boot it freeze in "Starting windows" i tried for hours and it seems impossible. what i learned is I have to enable legacy/csm boot in BIOS but I cant find the option in bios. Tried to disable secure boot and fast boot, i did everything i cant see it i tried to mod/flash bios with AfuWin64 and AMIBCP and/or amiflash, but when i made changes and apply them I get error 10.

Is it impossible? Should i return this crap?

Here is my current bios settings: easyupload"DOT"io/c6a16f (saved with AfuWin64 3.05.02)

i will pay your dinner with btc for the quickest and best help im going crazy here

and my current bios driver: dlcdnets.asus"DOT"com/pub/ASUS/nb/X421JAY/ASUS_X421JAY_301_BIOS_Installer.exe

I thought that install windows 7 on a intel 10th gen platform is not good choice and unrealistic , i've been not see any one install win7 successfully on this platform.
It should is lack of some drivers so it stuck , such as usb3 , xhci..etc ,old win7 install image are not include them ,so maybe you need to find a integrate drivers win7 iso in the internet then take a try.

I can't found out any related legacy or csm options on this bios , i feel that unlock Advanced tab or Chipset tab to get more options is better.
Or you could tell me what's you need options in amibcp's menu structure.

There is lack of one variable value we need to know on this bios ,so maybe the mod can't reflash ,do you wanna test it??
If yes ,use this tool to dump bios and attach.
