10.5.2 Installation help

[xx66stangxx]

Ok so I downloaded 10.5.2 from the bay and I burned it in Roxio. I booted up with the dvd and opened disk utility there I reformated my hdd (to get rid of my old 10.5.1 install) and re-partitioned the drive. customized my install with Nvidia 320 mb driver, MBR bootup, nforce driver and x11. The installation only took about 20 mins if that and rebooted after. After that I get the blinking curser and so I thought maybe I had to activated the partition so I did
fdisk -e /dv/rdisk0
update
f 1
w
q
reboot
and whe I reboot without the dvd I still have the same issue.

Any suggestions?
Right now I have 10.4.10 installed and I'm typing from it right now.
