How can I dual boot Windows 7 and iAtkos v7 with Windows 7 preinstalled?

My specs are:

AMD Athlon II X4 620 Processor 2.60 GHz
6GB DDR2 RAM
500GB HDD
Nvidia 9100 integrated graphics with 256MB dedicated
Windows 7 64-bit
HP Pavilion p6247c-b

Any help is greatly appreciated thanks.

Try EasyBCD.

I have it, but how should I partition my drive and install it?
