Hi ybloi,

 

to troubleshoot your problem further you basically have to connect a console cable to your box and observe the boot process to see where it stops.

Via console you may also enter the EUD (End User Diagnostic) to check your hardware.

If the boot loader can't find a bootable partition, you may also try to enter the F5 Disk Erase Utility to check if the hard drive is accesible (do not erase anything, just check if the utility displays you a disk).
