It all works well, with the need to hide boot.ini in order to boot Android, and restore boot.ini in order to boot Ubuntu : Ubuntu is still very fast with this 32 GB Sandisk SDCard (advertized as 48 MB/s). However, since my eMMC is the smallest one (8GB), I have used a somewhat different partition setup than the ones suggested in the 'Dual boot' posts : the boot.ini for Ubuntu is added to Android's partition 1, whilst Ubuntu's root file system has more room in the SDcard. So, it seems better to boot both OSes from the eMMC module, and have the bigger SDcard for user storage. I've effectively noticed that when booting from the eMMC, the eMMC is associated to /dev/mmcblk0 and the SDcard to /dev/mmcblk1 (whereas the SDcard gets the /dev/mmcblk0 when it is alone).
Hi, I've experimented a bit with dual booting of Hardkernel's images of Android and Lubuntu with both the eMMC and a SDCard installed.
