Hi there, I have 1 primary HD with 2 partitions on the active partition C I have XP Pro installed I’d now like to install Vista on the second partition which is currently hidden. According to what I’ve read here I should use the OSS to hide the current active XP Pro partition and set the second currently hidden partition as active. This I have done but then when I start to install Vista it shows the first partition with XP Pro on it and of course the second partition. So I assume that will mean that if I carry on loading Vista on the second partition that it will install its own boot loader which is not what I want, I want to use the Acronis boot loader. Any hints or instructions on what I might be doing wrong and how to rectify the problem? Many thanks, Tim.
