PC Having trouble booting

[d00f]

Hi,
When ever I try to start my new computer, it says " PXE-E61: Media test failure, check cable
PXE-M0F: Exiting PXE ROM

Reboot and Select proper Boot device or Insert Boot Media in selected Boot Device and press a key "

The computer was supposed to come with Windows 7 already installed if that helps.

Probably a nooby question, But I would like some help with this

That error message means that the PC is configured to boot from network via LAN port. Go to BIOS and adjust the boot order so that the PC boots from the HDD.
