Dual Boot Windows and MacOS sharing same Storage HDD

[TronEffect]

Hey guys, my system is dual boot with Windows 10 and Mojave with both on their own SSD. I have a 5TB HDD that i want to use as storage internally. Is there proper way where i can use it for both OS as a shared storage drive?

Yes this for internal. Right now I actually have half of the HDD partitioned for Windows 10 NTFS, and, when I am in macOS in disk utility, it does not see the other half that is free for me to partition it for macOS. It see's the NTFS that i allocated for windows...

Nvm... i finally figured it out... went into windows and added a EFI and then returned to macOS to reformat for macOS... great!
