MP 1,1-5,1 Current best way to install Windows 11 and MacOS on Opencore with separate SSD's on cMP 5,1

[Vega20]

Hi, this is a follow up question from a couple days ago. I am currently running 12.3 with Martin Lo's packages and cannot seem to figure out how to get windows 10/11 on a second SSD. I've tried to create the exFAT USB method for Win10 from here https://forums.macrumors.com/threads/opencore-on-the-mac-pro.2207814/ and apparently either Rufus or Microsoft has depreciated Windows to Go so I can't install from a PC. A normal Windows 11 USB does boot but throws errors when I get to the partition phase after bypassing the CPU/TPM checks and that may still cause the corruption problems. What is the current method of installing EFI windows? Thanks!

Also, are the latest brigadier packages working fine or do I need older ones?

I did a TON of research into this, there is a lot of stuff on reddit, and on other hackintosh sites as well on this topic, so you should be able to find many guides on how to do it. Here is what I did: After getting OpenCore running on my Mac SSD [which sits in an OWC PCIe adapter in PCIe Slot...

The method in the OpenCore thread uses neither Rufus nor Windows to Go nor a PC and works for both Windows 10 and 11. In fact, I just did a fresh install of Windows 11 with it!

Hi, do you mind to share how you step-by-step setup the Windows 11 by using OpenCore on cMP 5,1?
I used Martin Lo's package (v0.8) to successfully install Catalina & Monterey yesterday, and now intended to install Windows 11. But in this guide: https://forums.macrumors.com/threads/opencore-on-the-mac-pro.2207814/ it's not the same config.plist of Martin Lo. Thank you in advance.

Hi, I just ended up installing through Rufus on another PC as Lo’s latest packages kept freezing if a USB was plugged in on boot. I followed the first link but used my SSD instead of a USB and then reset windows from settings after first boot to remove the Windows to Go drivers.

Bootable drives can be created in multiple ways depending on different scenarios. The most popular utility software used to create bootable USB drives are Rufus and EaseUS OS2Go.

Afterwards I used the latest iMac Pro 1,1 bootcamp as per here and it worked wonderfully. Hope that helps!
