It appears you did not have your hard disk controller drivers properly installed or changed modes in the BIOS. Have you changed modes from IDE to AHCI, by chance? If not, it was probably just that the drivers were not installed.
I would recommend you update all possible drivers available through the Intel driver update utility. Ignore only those that say they are not supported or the device is unknown.
I haven't change IDE to AHCI what i know..
How to do that in a proper way then?

To get it clear.. I didn't find that Intel driver you talked about, but i saw that this other one did pop up in the device manager. After reboot i saw my windows using this "unit drivers" (think it's called that in english) if that's why..
