i've trying to upgrade my laptop to windows 7 with no success, currently i'm running vista, i tried the 32 and 64 bit versionbut its still the same, error i'm getting is "i need to have at least service pack 1 on my system, i updates all the stuff that needs to be updated, i chat to one of the sony tech support and he said that this model of laptop does not support any other os besides what it came with..is that true? thanks
