Chromebook and LinuxCNC

Debian LinuxCNC just wouldn't load Flash Drive legacy BIOS, with HP 15 notebook, Win 8 OS and Insyde UEFI. Ubuntu 16.10 did load legacy BIOS okay and operable. I tried to install Oracle Virtual Box onto legacy of boot of Ubuntu 16.10 but it didn't work.

I suppose required is Ubuntu OS if to load Debain LinuxCNC both separate boots.

RTAI might not interfere with loading Debain LinuxCNC yet because it loaded with Chromebook and only USB ports but trying to open LinuxCNC did error probably due to RTAI incompatibility.

GB-BXBT-1900, pamphlet instruction, Brix Driver (UFEI/BIOS) install DVD, default and option Windows 7 or 8. I don't know if default has a list of other OS. Is Ubuntu OS okay with Brix Driver? The mini-PC includes an Intel Celeron J1900 CPU. I guess Linux OS has been structured to boot up with most drivers. Is it necessary to use a Linux Driver to boot up Ubuntu with this CPU, if is, where is download? I went to Intel web site, searched for Linux Drivers and only is Firmware Processor Microcode Data File. Is that File a necessary update with any Driver if using Linux OS?

I would just try the stretch ISO image on the GXBT-1900, it should work as is.
You may need to unplug/disable the built-in wireless card if one is included

That will be fine. Pretty sure its the exact model I'm using with my 7i76e
The Wifi card will cause massive latency so remove it and use a USB wifi dongle.

As Peter said, the iso would be what I would try first

I was considering if installing a recent version of Ubuntu on internal hard drive which, is a added accessory to GXBT-1900. Idea was if Linux CNC would boot up with dongle.

I think the ISO Peter linked to will make life so much easier for you.
