I recently tried to install 11.04 (64bit)from a flash drive.

It boots up and starts the installation normally, and after I select the option to install to Hard Disk, the screen goes black. (and I can barely make out the outline of the installation menu. with the language options and whatnot...)

I downloaded the ISO and USB Installer a few more times, but that that wasn't the problem. The flash drive is brand new.

I would appreciate any help.
