I had just used it like that on a previous MBR based system and it worked fine. I have just booted it using the USB stick again and removed both labels metadata using glabel stop and clear and changed the fstab to use /dev/gpt/ labels now. Unfortunately the same issue persists. It mounted fine, but when I rebooted it it synced all buffers successfully but then gave the same error saying that it couldn't unmount /.
