Does it do that before or after the Grub boot menu?

If you don't see the Grub boot menu, it's most likely a BIOS issue. 
Check the boot settings in the system BIOS and in the card's BIOS; if 
that doesn't help, you should confirm that your computer can actually 
boot from that card by doing a minimal install of another operating 
system, for example Debian (I suggest a squeeze x64 because if it boots 
you could actually upgrade it to Proxmox VE) or Ubuntu or even *cough* 
Windows (XP is enough).

Debugging is twice as hard as writing the code in the first place.
Therefore, if you write the code as cleverly as possible, you are,
by definition, not smart enough to debug it.
