Installation and dual boot with a preinstalled Windows XP

[dyngoman]

Good day,

I have 2 brand new Asus K52JT laptops with the following specs:
- i3 380M
- 4Gb DDR3
- HDD SATA II 750Gb
- ATI Radeon 6370M 1Gb

They both came with Free Dos installed.
On one of them I have successfully installed Windows XP , tweaking the bios to use the ATA instead of the AHCI controller. Generally the drivers work fine except for the card reader witch doesnt want to install. Being pleased with the results I have decided to leave the first laptop like this and experiment a little with the other one.
What I want to do is use nLite software to inject the SATA drivers into an Windows XP installation iso to enable the AHCI controller and install.
Then, if everything works fine I would like to install Windows 7 x64 on another secondary partition as the second OS.

The problem is that I am not sure witch SATA drivers i need and from where to procure them.

My question would be if anyone has tried something like this before and if there are any general rules or knowledge that i should be aware of.
Also, does a Windows 7 x64 installation messes up my XP installation ?

This is called 'slipstreaming' and you want to slipstream your WinXP to SP3 which has SATA drivers installed.

WinXP/Win7 dual boot works fine and is easy to setup. Just follow the installation guides for dual boot.
