Catalina partition becomes unbootable and turns into "disk0s2"
I was dualbooting my MacBook with Catalina and Mavericks - install went perfectly fine, until I had to restart the computer, and discovered my Catalina partition is completely gone from the boot picker!
At first, I simply thought it was due to APFS not being recognized - however even with a Catalina install USB, it shows the Catalina partition as “disk0s2”, and I can’t write or install to it. Only the second Mavericks partition shows up. Using the
diskutil list disk0 command in the terminal (lists partitions on disk0, the main drive in the computer) shows the same partition as
It seems as if the data and the partition itself is still there, only it’s unable to be booted from. Now how do I boot from it? I apologize if the information given isn’t that much. Any help is really welcomed.
Edit - my Mavericks partition is still bootable. Only the Catalina partition - which doesn’t show up in the boot picker in the first place.
