I installed another Windows 10 Home OS on an external SSD 500GB. It obviously connects via USB. I did this because the internal drive on these streambooks are too small...mine only having 32GB. I successfully installed the OS on the external SSD and I'm able to boot from the SSD manually via the start up menu by pressing the esc key and going into the boot devices. This is unfortunately only a one time boot option. I need to find a way to tell the BIOS to boot from the external USB SSD all the time without asking it too every time I turn on the computer via the start up options...any suggestions?
