I think I tried all combinations and all my knowledge but no luck.
I dont want a virtual OS.
wantto dual boot on a HDD (possible 2 partition)

is it possible or not ?

ofsure two harddisk is not problem.
but what if PC have only one HDD ?
not possible ?

(thank you)

According to my experience, it's possible.

Firstly I install Win 7 as normal, in a partition. Then using iATKOS - Mac 10.5.7 (burned as ISO to a DVD 4.7 GB) and install the Hackintosh in another one.
Remember to uncheck the "bootloader" option while installing Hackintosh.

Then, reboot and Win 7 will show its face as usual, then download the Chameleon bootloader for Windows (attached file from this topic [Chameleon Install 3.0][Windows install Chameleon] - InsanelyMac Forum) and install it (on Win 7).

After rebooting again, your menu should be something like this:

Win 7
Chameleon

Enter "Chameleon" entry and you'll see the OSX boot option.
Hope this help. I'm currently trying to move my work onto a USB stick ^^
Sorry for my bad English...
