I have bought HP 2550EN PAVILION latpop. I cannot run some programs so decide to configure dual boot or downgrade..! But it has phoenix BIOS, when contacted HP Support UAE, they gave no support regarding how to do this. This cannot be done..! When I tried to boot with bootable XP SP2 cd having SATA drivers configured from f6fply32.exe by nlite software , even that the Hard drive is not detected by Windows XP OS. So please advise how to downgrade or dual boot ? Br, Chirag
