Hey, folks. I successfully set up my X86 II with a fresh installation of Ubuntu on SD card. I followed the procedure in the Udoo directions and it worked without a hitch. Then, I tried an Android installation. This involved removing the SD card with Ubuntu on it, of course. But, my machine still boots to Ubuntu even though the card is removed... So, WHERE is this OS, actually? Is it loaded into a section of the onboard EMMC? IF there is something on the EMMC (or elsewhere), how do I go about dual or triple booting (Ubuntu vs. Android vs. Win10) without wiping out one OS or another one? Is there a multi-boot guide posted anywhere? Lastly, I have a rare Sandisk A110 SSD (PCIe 2.0) installed, too. And, soon I'll have an external SATA attached. Some advice about where to strategically install each OS would be really helpful. The main OS will eventually be *Android*. But, easy switching from one to the next is what I seek. How is this done? Thanks,
