Startup Disk not recognized

At startup my OSX partition isn't recognized.

When booting up in Recovery Mode, in Disk Utility I see the partition as disk0s2, and disk1 with Mac OS X Base System. When attempting to Verify or Repair disk, the same results show: "Verify/Repairing volume failed: Unrecognized file system."

It doesn't allow me to restore macOS X, only reinstall, but there are still important documents that I need.

Any suggestions or help would be greatly appreciated

MacBook Pro 13″, macOS 10.13

It turns out the Partition Table of my SSD was modified when I, according to Disk Utility's output at the time, "successfully" partitioned my drive.

Yes, even with "Show All Devices" selected it doesn't show.

I should add that this happened when starting up in Recovery Mode with Option + R. When starting up in Internet Recovery Mode, not even the disk0s2 and disk1 are recognized/shown in Disk Utility.

In Disk Utility's View Menu, have you chosen Show all devices?
