Description Vurefozu 2022-11-18 06:59:47 UTC 
Hello.
Trying to install FreeBSD 13.1-Release (FreeBSD-13.1-RELEASE-amd64-disc1.iso) with configuration:
Partitioning: Auto (ZFS)
Partition Scheme: MBR (BIOS)
Pool Type/Disks: stripe: 1 disk

And I found that after the first reboot the system does not boot and a message is displayed: "Missing operating system"

Solution: manual installation according to the instructions https://wiki.freebsd.org/RootOnZFS/ZFSBootSlice

Tested with FreeBSD-13.1-RELEASE-amd64-dvd1.iso 
in VirtualBox. Condensed steps:

1. install, as outlined in this bug report

2. reboot, live CD

3. zpool import -R /tmp bootpool

4. zfs list

5. observe a sole dataset

6. ls -hl /tmp/bootpool

7. observe a sole file, a directory: 

boot

(That can't be correct, can it?)

Attached: a comparable typescript.
Comment 2 Graham Perrin freebsd_committer freebsd_triage 2022-12-05 02:03:25 UTC 
Triage: severity reduced, given the workarounds. 

(Vermaden's might be the simplest – prefer 'GPT (BIOS)' when installing.)
Comment 3 Vurefozu 2022-12-05 14:26:07 UTC 
(In reply to Graham Perrin from comment #2)

There is no problem with "GPT (BIOS)". The problem is with automatic installation via "MBR (BIOS)".

Yes, I have the same.
