Hi! I just acquired a Lenovo Ideapad 3 with 11th Gen Intel Tiger Lake processor and Intel Iris Xe graphics and I was wondering if it was possible to install Windows 7 to it. Unfortunately, I do not have Legacy Mode so it has to be done in UEFI mode. The ISO I use has all the updates up to 2020 EOL integrated along with drivers such as Nvme, USB3, etc. It also replaces the Win7 PE with the Win8.1 PE (Windows 8.1 was tried first and installs fine). I whip up the USB as GPT in Rufus and put in the UEFI7 1.3.0 files, I install it, boot back into the media, use Shift+F10 to open up command prompt->Diskpart to assign a letter to the System partition and then a command prompt->Notepad->Open->All Files to the Windows 10 part to copy the UEFI7 file to the microsoft/boot folder on the System drive. After exiting, it tries to finish the Windows Logo, but it restarts. When I use "Disable Automatic Restart After System Failure", it simply gets stuck on the incomplete Windows Logo. When I whipped up a Windows 8.0 (6.2) GPT USB, It actually showed me the BSOD, which was NON_ACPI_COMPLIANT_BIOS, meaning this is also most definitely the case for Windows 7. Is there a modded ACPI driver for Windows 7 to get it to run on hardware such as Tiger Lake? Also, has anyone modded graphics drivers that work on Intel Tiger Lake and Windows 7/8.1? And is there any way to get the HID-Compliant touchpad/touchscreen working under 7? Both of these devices do not work under the Windows 7 8 PE nor under 8.1's PE or even an installed copy of 8.1 (the earliest these devices work is with Windows 10 Build 10240, or the free upgrade build given to us in July 2015). Any help on this would be greatly appreciated! I was inspired to start this after seeing the work being put into getting Windows XP to work on modern hardware. Since Windows 7 was the second most popular operating system after XP, I hope this can go somewhere. I would love to use Windows 7 on a 2022 laptop complete with working ACPI, Aero Glass, touchpad, touchscreen, and any other driver I may need (those will be discussed further down the road after we get the four important ones working).
