hp pavilion dv4t 1400 Won't Recognize Hard Drive! Help Please?

I recently downloaded a copy of hackintosh leopard 10.5 ox from bittorrent i installed it on my laptop it would dual boot but then nothing would show up if i selected Mac os so i decided to go into windows and i deleted the mac partition and format the partition. I restarted my computer and the all i kept getting was boot loader error. boot 0 error.
i tried install windows 7 onto the laptop but my laptop won't read the hard drive at all it shows nothing. i even went to the point where i bought 4 hard drives tried them all nothing. if anyone can help please help me i am stuck.
right now am running ubuntu from a 8gb flash drive.
