ok my friend its not that easy but its always possible
fisrt just to know why u r unable to install xp because u have the HARD DISK SATA
and windows xp wont detect it because there are no definitions for SATA HDD.
so what should we do to fix this problem, you will know that by following these steps:
at the begining you need a floppy disk and floppy disk drive (i know thats not available in the new laptops, so u might need to buy one).
ok now we will need to download the SATA definitions from here:
and save it in the floppy disk (dont forget to unzip the file first).
now lets start the windows installation process (as usual).
u before you get to load the windows file there will be a prompt (in the buttom of the screen) asking you (press F6 if u need to install a third party...........) now press F6 quickly.
you will have a new screen with three options (S= specify, enter= continue or F3= exit).
now lets press S.
you will have a prompt asking you to (insert the labeled disk manufacturer ................).
lets insert the floppy disk now. and press enter
and when its asking you to select definition, select RAID driver.
and when its asking you about windows logo testing press yes.
and after finishing the definition process it will detect the HDD.
now continue installing windows as usual
enjoy XP (i know its a long story but its worth it :)
sure let me know what happened with u and for any other problems plz let me know
