Original Question:
I am trying to install Mac OS big sur along with my windows 10. I have been following dortania's opencore guide along with a youtube video for the entire process. I managed to boot into my usb but get "busy timeout" error along the way and it takes 10+ minutes to just get into the GUI everytime.
Even tho I get into the GUI, I can't find my HDD or SSD in the disk utilities.
Specs:
Acer Predator Helios 300 i7 7th gen Nvidia GTX 1050ti I have a 128gb ssd where my Windows 10 installation is located along with a 1TB hdd where I would like to install mac.
Images:
Here is the image of the busy timeout error which I suspect might be the cause: busy timeout
Here is the image of the disk utility screen which I get: Disk Utility
