My name is dave, and I'm new here. I've a question. I know you get a lot of threads about dual boot, and I'm sorry. but I did search and couldn't find any mention of this particular aspect of dual booting.so here goes.... I installed two instance of xp on two different partition (same hd). The idea was me and my brother will have each a different, separate XP. He won't be able to get into my files and vice versa. Also, he will be able to install his games, and I, my programs without slowing the os down. Yet, I can't get windows to hide his partition when my xp boots up, or his to hide my partition. I tried using acronis OS selector, and it did suceed in hiding his partition (d) from my XP which sits on c, but not the other way around. It seems like the first partition has to be visible to any OS on the HD since the BIOS start booting from there. Any workaround?
