Windows7 Installation on Icelake [ Lenovo Thinkbook15 IIL ]

Recommended Posts

        Hello, everyone ! These days I am trying to install Windows 7 on my thinkbook15iil. Before that, I have read some posts about the installation  and learnt that there are several diffculties to achieve the goal :

  • A5 BSOD caused by ACPI [1]
  • stuck on Win7 logo because of the lack of gop support in Win7 [2]
  • [Already Solved] Integrating drivers into Windows7 installation media [3]
     After I got the basic usage of OpenCore, the open-source boot manager of modern machines, I have some new ideas:
             Is it possible to use OC to avoid the chaoes[2] in Windows7 installation?
             Is it  feasible to bypass chaoes[1] caused by old ACPI.sys?
             Is it necessary to unlock the advanced menu of UEFI-BIOS of the computer? The feasibility? And if the answer is positive, how to do it?

Hello and welcome here,


What is the purpose of running such an old OS on such a machine ?


With this tool, you can install Windows 7 with the boot.wim of Windows 7, maybe that will help with installation: https://forums.mydigitallife.net/threads/mdl-win-7-tool-for-simplix-updatepack-aio-iso-with-install-wim-esd-creation.79421/

And when it comes to register in MDL, a dreadful problem occurred: I was always regarded as an automatic program even after passing the recaptcha procedure. I tried to contact MDL forum's hoster, but got no replies.  How can I solve this ?
