So, I've stayed up all night trying to get Ubuntu on my microSD card. I succeeded, my 4GB is partitioned into two partitions, one that is 32mb and set to boot with the three files needed, and the other that is 3gb+ and has the operating system files in it. I followed this page exactly. It is strongly based on this page, so I am assuming it is correct.
So I've put my USB hub on the gumstix, got my monitor connected, and the SD card in the slot. When I boot up, it boots directly to the OE/Whatever preinstalled on the SD, which according to a previous responded was corrupted. It doesn't even notice the SD card. I am suitably frustrated.. What can I do?
