Original Question:
Hello, so I've managed to successfully install Big Sur via this guide , to a partition of my second Hard Drive on my laptop which is an HDD with opencore. After that, I installed Windows 10, on my main SSD drivers on my laptop.
The thing is, now that I've installed Windows 10, I can no longer boot to MacOS, as I'm not given such option.
I want to be able to choose which OS to boot when my Laptop first boots up, can anyone help me with dual booting?
