Windows install error

Before i begin, here's my system spec:

System type: desktop
Manufacturer name: Acer
Model: Aspire X1200
BIOS/Firmware Maker: Phoenix Technologies, LTD
CPU: AMD Athlon LE-1600 processor
64 Bit: true
System config: Sun microsystems i86pc
RAM: 1GB DDRII
HDD: 320GB SATA
Video: Built in graphic, Nividia GeForce 8200
LAN: Integrated Lan 10/100/1000

I get this 0x0000007B error which I am sure is caused by the SATA disk but I don't know how to go about it in slipstreaming the correct driver(My pc doesn't have a floppy disk drive therefore I am forced to slipstream.) because the driver i downloaded is a .exe file not an inf file as nLite is looking for .inf file if i remembered correctly. I got confused reading all the threads I found that has similar problem to mine so I decided to post here for help.

On the side note, I have no problem installing opensolaris latest version (as a matter of fact, all the linux distro i installed) except that i cannot connect to the internet. Here's the link if you are interested: http://www.opensolaris.org/jive/thread.jspa?threadID=75307
