After trying to install Windows via Bootcamp on (yes I understand what "beta" means) beta High Sierra 10.13 I was left with unbootable partition:
I cannot mount this disk. It's shown as "Mac OS Extended" file system though it was APFS. (The Untitled is the partition with newly installed Mac OS version via internet recover.

I have run two checks.
sudo fsck_apfs -fy -x /dev/rdisk0s2
sudo fsck_hfs -fy -x /dev/rdisk0s2
I understand that I deal with beta software, and I should not expect to recover lost partition, but nevertheless I would be grateful for suggestion, what to do to recover this partition.
