I recently installed Ubuntu onto a 16GB flash-drive. I am not talking about a liveUSB, I mean I installed full Ubuntu onto the drive. My problem is that when I have tried booting from the device, all I get is the black screen with the flashing "_" in the top left corner. This persists for at least 15 minutes (at which point I give up). I outline my process for creating the USB below. My question is what exactly could be causing this, and how can I fix it?
From a different liveUSB I chose the install option, after the timezone info and others, I chose "Something Else" for installation type. On the single partition of my flash drive, I chose "ext2 file system", checked the format drive box, and set the mount point to "/"(the root). After warning me about not having a swap partition (which I was told would not be a problem), I went through the rest of the install without a single issue. But now when I boot from the drive, I get the persistent blank screen.
