Yup, dual boot on two SSDs is easy to do.I have a question. My main is windows as I play lots of games. I do have a seprate ssd which I can test for the mac but how should I start doing it ? Windows is already installed on main ssd. is their a way that I can do things without loosing windows and its data and making it a dual boot system.
Follow the Dortania guide for full instructions on installing macOS: https://dortania.github.io/OpenCore-Install-Guide/
As you already have Windows installed and are installing macOS on a second SSD, you can follow the above guide exactly - there's nothing special you need to do. Just be careful when you get into the macOS installer that you format the right SSD! To make things safer, you could even unplug the Windows SSD/NVMe drive before installing macOS, just to be sure you're not wiping the wrong drive. Then plug it back in once macOS is installed.
After following the Install Guide you'll be booting macOS, via the OpenCore bootloader, from a USB stick. After that's done, move on to the Dortania Post Install guide to get everything fully working. One step of that Post Install guide will show you how to copy the OpenCore bootloader and config to your macOS SSD, at which point you won't need the USB to boot any more (though always keep it around as a backup method of booting macOS.)
From that point onwards you will be able to choose to boot either OpenCore (for macOS) or Windows from your BIOS boot picker.
Or, you can choose to boot OpenCore always, and then choose between boot Windows or macOS from the OpenCore picker. However that does mean that, at least by default, OpenCore will change your motherboard name in Windows and you might need to re-activate Windows. Personally I prefer to boot Windows direct from the BIOS boot picker, and only boot macOS from OpenCore.
In no scenario should you lose any Windows data, and in future you'll have an easy dual-boot setup.
