Reboot when installing problem

[TheSpecialist]

Hello,

 

(I'm so sorry for my bad English)

 

I've downloaded some versions of modified Mac OS X Leopard for install this on my new PC.

Its hardware is:

 

-I've build it myself-

 

Motherboard MSI-7366

Intel Code 2 Duo E8400 @ 3.00 Ghz (SSE, SSE2, SSE3)

Nvidia GeForce 9800 GT 512mb

2048 mb DDR2 RAM

Hard Drive Hitachi 500gb

External Hard Drive Storex 200gb

 

I've tried with iATKOS 1.0, 4i, 5i, and some others but there is the same problem:

My PC automaticaly reboot when I pressed "F8" then "-v".

 

What can I do? Should I trying to modify something in BIOS?

 

(Please note I want to install Mac OS X on my External Hard Drive Disk)

 

Thank you very much
