Getting BusyBox when trying to install Natty from USB

[eks]

I've tried both the DVD and CD, the CD with both usb-creator-kde and unetbootin. The results are the same always, the USB boots, into the splash screen, I select Start Kubuntu, it goes to the loading screen. After some seconds it starts scrolling a wall of text, gives some error about not being able to write or read /root/var/* because they don't exists and end up on a BusyBox with (initramfs) prompt.

What gives?

I need to install the system on a new disk (2tb) instead of upgrading because I have to send the current one (1tb) to replacement. Could the large 2tb disk be a problem? I tried unplugging all disks and leaving just the disk I want to install to, but no deal...

(Checked the md5sum and they both match for DVD and CD...)

Try typing "exit" (without quotes) at the prompt.

Looks more like the creation of the LiveUSB wasn't done properly.
