Automatic continuos reinstalling, again and again

I've a problem...

I'm trying to install Mac OSX 10.5.1 Leopard iAtkos v1.0i on a Virtual Machine in VMware...

I've done this step:

Patched the .iso file with the iATKOS_v1.0i_AMD_Test.ppf
Created the machine, mounting the iso file as CD-rom device, and start installing.

With disk utility I partizionated the virtual hard drive, creating one partition called Leopard and setting it to MBR.

AFter this I started the installation. It goes pretty fast and well, but after the reboot the virtual computer seems like i've never install anything, asking me again to install the OS. the only different thing from before, is that on the virtual hard disk there is 5-6 Gb of Used spaced (i guess the OS file installed before). In startup disk utility doesn't see my bootable hard drive...

What I have to do? , I'm in your hand...

My virtual machine main settings are:
1 processor, 2 cores
30 Gb hard drive
1024 Mb Ram

My phisically machine main setting are:
AMD 64 X2 Dual Core Processor 5600+ 2,81GHz
WIndows 7 32 bit (i know, just 32 bit...)
and some kind of mother board that actually i can't find the name... but if is necesarly i will find!

thank for your help, and sorry for my english, i'm not from UK or USA, i'm just italian!
