    What I don't understand is that my driver Msahci.sys is Started in Regedit ( start = 0)

    As stated in this tutorial

    Solution for SATA blue-screen in Windows 7


    ; When I check the drivers of my Disk ;
    I can see

    disk.sys
    partmgr.sys
    PCTCore64.sys ( unsigned)
    snapman.sys ( unsigned)

    I'm kind of lost why is there 4 drivers and no sign of Msahci.sys ?

    I have tried to update the drivers showing the path into system32 , but that didn't work , because the driver update is looking for an .inf

    So far the HDD works

    I'm not quite sure I understand where you're going with this.

    The msachi.sys is loaded upon startup of Win7, but not XP. So, even though you find the driver in regedit and stuff, it means nothing when you try to boot into XP using the install disc.

    You already know that XP does not natively support SATA, and that's why you slipstreamed the drivers. Did you slipstream the correct drivers? I used iastor.sys, as provided from Intel in the F6 install version on the support site.
