HASS.IO -> transfer from SD card to SSD or USB

Take a look here:

Rpi 4 installation

The only way I got SSD booting on Pi4 is to go with Raspbian Buster instead of HassOS and then install Hassio on top. The caviat is that you will still have to have sd card plugged in to boot but then everything will run of SSD usb. I got a Kingston A2000 NVMe drive (it’s pretty cheap considering the speed you get) and Shinestar adapter for it . While you are there pickup yourself this bad boy heat sink case Pi4 runs much hotter then pi3 and will throttle, and you will be back at pi3 speed …

Yep, Pi4 is only bootable from USB, if you leave a microSD in it.
