Try burning the iBoot iso onto a CD-R. This is a bootloader that autoloads some common drivers. Tell your PC to boot of the CD and when the menu pops up, choose your OSX Installation.

Then it will load and you'll be able to log in. Next, on the same site that you can download iBoot, download the program called Multibeast. This will install all the same drivers that were loaded when you used iBoot to boot your OSX.

to know which options to choose on the installation.

At that point, you should be able to reboot and boot into OSX normally and everything should be good.
