Coming from Windows machines, I have been tooling around on an old MBP 8,2 for a while just as a toy and learning experience with OCLP and other OS's. It's been fun to have a machine that I can mess with without consequences.
I had it dual booted with Linux Mint, which worked pretty well until something happened a while ago - I don't know exactly what, but I think an OCLP update may have upset the EFI partition and left my Linux partition stranded. As I didn't have a burning need for the Linux boot, I carried on using the machine as Mac only.
Enter tonight - i got curious and looked into getting the Linux boot back into action. I threw a hail mary and tried "diskutil repairDisk disk0", based on a thread on Apple support community... I now get the attached when attempting to boot up the machine - no MacOS, no Linux, nothing.
I'm fairly certain all my data still exists in all of the Mac and Linux partitions, I just don't know what my next steps are. I have a Time Machine backup from a week ago, so I'm not adverse to a wipe and reinstall. Ideally I'd like to dual boot again with Linux Mint.
Any thoughts on how to recover this?
