I am pretty sure this has been posted before but I cant find the right topic so I am just going to ask again. So I have a HP Pavilion DV9540EB with vista(sigh) so I tried to install XP but I get the good old "cant find physical HDD" error, so I downloaded all the XP drivers from HP but they are all EXE files but yeah I need INF files I tried using winrar to open them no luck soo yeah im screwed badly
