Catalina has been running stable on this build for many months now, and Opencore updated to 0.6.4.
I'd like to install Big Sur on a different SSD so to keep my Catalina build, incase anything goes wrong as I need this machine for work....I presume this is straightforward?
I assume I follow instructions in post #1 under
Create Your USB Installer And Install macOS, with my current EFI folder in the USB, and install Big Sur on the other SSD.
However, do I need to do step 10 (Copy the EFI folder from the EFI partition of your USB flash drive to the EFI partition of your main system drive.)? If I leave the boot order as is in BIOS, will my current EFI on the Catalina disk give me the option to boot Catalina or Big Sur?
Thanks.
