When I attempt to find this partition (on Macos), here's what it's showing me:
/dev/disk3 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *15.8 GB disk3 1: Windows_FAT_16 RECOVERY 1.5 GB disk3s1 2: Linux 33.6 MB disk3s5
It looks as if s2-s4 are invisible. Is this where the boot partition is? It does not seem to be s1.
I just need to touch ssh on this so I can get a shell... I don't have a monitor/keyboard to do that with, and I don't have a linux machine which might make this easier.
