from Dual Boot to Triple Boot (different HDD - 2nd MacOS install) - OC 0.6.6

[B-Low75]

Hi there,

First port for me here so please correct me if I'm not in the correct forum.

I've made some research here before posting but couldn't find exactly the response to my issue.

I have a successful Opencore dual boot system (Win10 and Catalina 10.15.7) both running on separate M.2s.

I would like to install another instance of Catalina (the exact same EFI) on another SSD but I'm not sure how to proceed.

Should I use the same bootable USB key I've used to install Catalina and select the 3rd SSD when prompted to install?
Or should I use the recovery mode from the OC menu when booting?

Kind of scared to ruin something in my stable config...

My computer: Intel i9 10850k - Gigabyte z490 Vision D - Radeon RX 580 - opencore 0.6.6 - Windows 10 Pro - macOs Catalina 10.15.7

Thanks a lot!

Hello,

Easier thing would be to just clone your existing Catalina install on another SSD.

Hi Ben42, I've gone ahead and used CCC and it worked perfectly well,

Thanks a lot!
