i got this soft ware off a freind
but how do i make it work Lol
i tryed it on a comp with win 98 and made some thing with the extention .vhd file and when i go to the start up the os says cant find os install os or some thing
and the help file seems to really suck Lol

yea i know the .vhd is about 3mb and cant possilby fit win me in it so i dont what the helll am ment to do with this thing lol

ok i know how to do now
but if i install win xp will it replace any thing
you know when you install win xp then you install win 98 and it only starts with win 98 and you try to boot win xp and is says crap about hal.dll or some thing
understan????????
