MANY MANY THANKS, betacentauri!
Thanks also for the quick replay!
Now, thanks to you, I can see the "partitions" as you describe:
linuxrootfs1
linuxrootfs2
linuxrootfs3
I guess, the fourth Partition is D: minus the above three, plus the Android one ...
Culd be possible to manipulate the boot loader so that the space for the partitions can be created on a USB instead of the flash where its created?
If so, how ???
