Accessing internal macOS drive in macOS

[Itay113]

Hey everyone,
I've just installed macOS big sur on my 240gb ssd and I have another drive with 1tb that has on it macOS catalina.
Now I am trying to accessing via finder but it is not appearing in it, tried to go to Disk Utility and I tried to press mount drive but it gives me error..
Btw, both macOSes used OpenCore (Catalina - 0.5.9, Big Sur - 0.6.3)

Hi there,

Something doesn't look right. Your disk2s2 (Catalina?) is in MS-DOS format. This would be okay for an EFI partition but not an OS disk.

Perhaps we are missing some information here?

Yes, it does. Why is a Catalina drive on a Windows volume? You can clearly see that. If it is a running system, from the other disk's EFI partition, then I haven't seen that before.

I don't know.. I installed it about 5 months ago and I am sure I erased the drive and formatted before installing catalina
