Okay, so totally weird. It must’ve worked at some point because I had to leave for a while but when I came back it was at the linux prompt. Here’s the lsblk command, sda is the system SSD.
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sdb 8:16 0 298.1G 0 disk
└─sdb1 8:17 0 298.1G 0 part
sda 8:0 0 238.5G 0 disk
└─sda4 8:4 0 238G 0 part
└─sda2 8:2 0 100M 0 part
└─sda3 8:3 0 128M 0 part
└─sda1 8:1 0 300M 0 part
When I rebooted it went back to the open timeout. So I have no idea what the deal is here.
