Freeze on boot

[kart0ffelsack]

I can boot and run pfsense from the live cd but after I installed pfsense on hard disk it will not boot.
The booloader just freezes without a error message in this state:

boot: F1
/

I also tried to install it with "packet" unchecked but nothing changed.

I have no idea what might be wrong but I can exclude a hardware errors as other programs run fine.

Tried that didn't work at all. But I installed pfsense on a usb-stick which is connected as a external hard drive… And guess what I can boot from the usb stick...
