after installing Ubuntu 13.04 (used 2 disks, 1 250GB for root and another with 2 partitions of which 1 with 10GB for swap) Ubuntu doesn't boot, showing a black screen with a blinking cursor two lines down (I actually saw the cursor going down two lines as if return was pressed).
The disks don't seem to be read although they are operational. I've installed twice this way already (a third try without any changes seem dumb to me).
These two installations occurred without internet access (I tried before with internet access but the system halted fetching file 28, whatever that means).
Thanks :) Sérgio Rito
