Im trying to install windows xp on this Sony VAIO VGN-FZ150E for my client. This laptop came originaly with windows vista home premium edition, but my client had installed winxp on that and have been running windows xp on this machine for about 8 months. He had some problem with the viruses and spyware. He wants me to format the hard drive and install win xp after the format. I tried to install the windows xp on this machine with different installation CDS. but after loading all the necessary drivers it stops and says "windows cant find a hard drive installed in this computer". I've taken the hard drive out and put it in a SATA enclosure and formatted and then put it back and tried to install windows xp but again after loading the drivers it says "windows cant find a hard drive installed in this computer".
What should i do to install windows xp professional on this laptop
