Raspberry pi 3B wont boot from SSD

Hello,

I bought an SSD and the rapsberry pi 3b works fine with raspbian on the ssd.
But whenever i install HA it wont boot.
I get the following error:

Someone knows how to fix this?

I have been getting the same thing. I had a system working, I’m pretty sure it was booting off of the SD card and then mounting the SSD, but a power outage messed it all up. I’ve been going through trying to get this all working again and came to the same thing. I don’t understand how it is that Raspbian has zero issues booting off of my external USB SSD but HA can’t get it together.
