[BUG]External Drive Full Boot

What Mac are you using?

MacBookPro13,3

What version of macOS are you using?

12.x

Are you using OpenCore Legacy Patcher?

No

What is your issue?

This is a bit confusing for me, and I’m not sure if this is a bug mainly because I am rather naïve about all this. I’m not much a techie, so please pretend you’re speaking to a donkey that doesn’t know much about anything when it comes to computers! Anyways, I’ll start with the basics and go from there.

As stated, I have a MacBookPro13,3, Quad-Core Intel Core i7. I didn’t install Windows exactly through bootcamp but rather created an external SSD to boot Windows exclusively. I used these instructions I found off youtube: https://www.youtube.com/watch?v=3IhW722IMwE

Now my problem is trying to resolve error 12, when trying to connect my RX580 egpu in Windows. I’m confused if even I should even be using Kryptonite because again, my Windows installation boots from an entirely separate drive and doesn’t exactly boot through bootcamp (I think, I don’t know, and feel rather pathetic I don’t know, fortunately or unfortunately -)

According to egpu.io, I did the DDU, and installed AMD drivers Red edition through bootcampdrivers.com. But I’m really stuck as to what to do next, as I really don’t want to harm my machine by turning these things called “pci lanes” (yes, I’m a donkey remember -).

I had thoughts about purchasing an NVIDIA egpu but, that’s a last course action. Ideally I want my current egpu to run in Windows. If you think Kryptonite will help, please let me know. Hopefully I can past this error 12 business.

I should also add, I kinda don't want to reinstall windows on the external drive all over again using the Kryptonite installer and I'm wondering if there's a faster to just get Windows to recognize the amd egpu.

Oh never mind this post. I got it to work! Had to deactivate one pcie (x8), so if you know of a method that doesn't require turning off an entire usb c side, I'm all ears. Otherwise please ignore this discussion.

Hello my Friend! I have the same problem. Please, can you help me? Are you show me what device do you disable? A image, maybe? Thanks for your support.

Unfortunately, I removed windows from my mac, with a fresh install of MacOS Monterey. So I don't have the capacity to take screen shots. I will say, go on youtube and search for "disabling pci lanes macbook" that should pop some helpful search results.
