macOS Installer can’t see partition created in windows??

Hey guys!

I’m pretty new to hackintosh, but I’m an avid computer user and decent at following directions so I decided to give dual booting a shot with my main Win10 install and an OpenCore hackintosh with Big Sur.

So far I have:

-Set up my USB with the installer files and EFI folder from OpenCore

-Configured my config.plist file using ProperTree and cross-referenced the results from the sanity checker

-Properly configured my Kexts and SSDT’s

-Created an exFAT partition using 250GB from my 2TB game drive

I can boot into the Big Sur installer just fine, but disk utility cannot see my partition I created in windows, even though it is exFAT. It just shows up as one big partition/unconfigured.

I would really like to forgo losing all my data on my game drive just to dual boot. Anyone have an idea of what the issue is?

For reference my specs are:

Intel Core i5-9600k

16GB Corsair Vengeance DDR4

EVGA GeForce GTX 1080

ASUS Prime Z390-A

Samsung 970 Evo Plus 500GB (Windows Boot Drive)

Seagate Barracuda 2TB (Game Drive/Where I want to install macOS)
