Hey, so to start with,
I have a gaming pc
and a mac.

My macs hardrive (bootcamped windows 10) wasnt working. So to test if its still alive, I plugged it into my gaming pc (set it as my first boot option) to see if itll boot.. and it did.

The issue arises when I unplug my mac's hardrive from my gaming pc, and then try to boot back into my usual drive. Windows 10 isnt booting to the login screen.

Ill make it past the windows 10 logo, but it wont go past the infinite spinning dots.. the worst would be for me to have to do a hard reset, and I hope I wont have to..
Any Ideas?

Thanks,
Adam
