Proxmox 3.0 Can't boot into installation UI

I'm trying to install Proxmox 3.0 on a HP DL180 G6 server that has the exact same configuration with my other servers that I run Proxmox 3.0 succesfully.

It tries to load the X interface and then return this error: Installation aborted - unable to continue (type exit or CTRL-D to reboot)

Here is the screenshot: http://imgur.com/4WEtzUo.png

Any ideas?
