MacOS 10.14.5 Wont Boot After Seemingly Successful Install

Hello all. I have installed OSX10.14 onto a 1TB HDD. My system now refuses to boot into macOS, only windows. I removed my windows drive and now it refuses to boot, period.

Some info - I have a core i5 8500, AMD Radeon RX570, an H310D motherboard, and only one HDD connected. Install was smooth and successful, using an offline installer as I do not have ethernet. On first install i was booted back into Windows but i rebooted and selected macOS and it finished installing, only to not boot

At one point i got it to throw an error at me, and i regret not writing it down. i will let you know if i get it again. Thanks in advance

Also, i am using OpenCore

EDIT: Got the error again! boot0ss: error_
