t480-oc VS OC-Little-Translated

First I have to say I really don't understand open core that much, I followed this guide https://github.com/valnoxy/t480-oc and now I have Monterey and Win11 on the same drive. But my problem is on the boot menu. In the first image if I choose Mac OS X nothing happens, with Open Core and NVMe0 it goes to open core boot menu and Windows Boot manager "tries" to boot windows (more on this later). The second image is the open core boot menu if I choose Mac os all goes well but is I choose window it end in a BSOD like the third picture. The only way to boot into window is to change the boot order and put windows boot manager as the first option (so booting to win is the default) and to boot to Mac I must go through the boot selector pressing F12 then choose open core, and then Mac os. Sorry for the long introduction. What I want is to boot to open core as default and then there choose win11 or Mac , so how can I fix the win11 not booting issue??? Thanks!!!

I can wipe MacOS off the drive or keep it on there and let you enjoy the wonders of MacOS on thinkpads. Your choice! (see for more info - https://github.com/valnoxy/t480-oc)

use this guide opencore

Take a look to this ( https://github.com/valnoxy/t480-oc ) and Dortania guide. I'll recommend you to use that repository as a base and after trying the system... To build your own configuration

So I successfully setup valnoxy's opencore implementation on my t480 (https://github.com/valnoxy/t480-oc)

Follow dortania then this https://github.com/5T33Z0/OC-Little-Translated/tree/main/01_Adding_missing_Devices_and_enabling_Features/CPU_Power_Management/Enabling_XCPM_on_Ivy_Bridge_CPUs then try boot again

See https://github.com/5T33Z0/OC-Little-Translated/blob/main/14_OCLP_Wintel/Ivy_Bridge-Ventura.md if you want electron apps, updates, filevault and everything working.

From the link you did provide I handle you this:

Also, check if you need this SSDT: https://github.com/5T33Z0/OC-Little-Translated/blob/4ef2d13a477de448e8f5337604602b668d9281c4/11_Graphics/GPU/GPU_undetected/Readme.md

This might help: https://github.com/5T33Z0/OC-Little-Translated/tree/main/11_Graphics/GPU/GPU_undetected

Hah, Common mistake, but easily fixable. Follow the ACPI guide. It's not perfect, but it covers all the basics you'll probably need. If you're interested in more, check out OCLittle's guide (translated by another user). The files are a bit outdated, but the explanations are great.
