I am having trouble getting my system to multi-boot as I'd like them to. I can't seem to get my two Vista partitions and my Win 7 partitions to play nice. Once I boot to Vista, I can no longer boot to Win 7. Can someone help get it right? I am using Partion Manager 10 Pro (build 7893) on a computer with two hard drives. The operating systems (o/s) have already been installed and work fine once I can boot to them. The first drive has: - Primary Partition 1 - VISTA Ultimate - 32-bit - Primary Partition 2 - Win 7 - 64-bit - Primary Partition 3 - VISTA Ultimate - 32p-bit The second drive has two partition which hold data and no o/s. Ultimately I would like my system to: - Be able to boot to each of the three o/s's - Not see the other o/s partitions from the one booted - Have the two data partitions always show as D: and E: If I am using PM's boot manager, I only want to see the O/S I'm booting to on Windows boot screen. If I'm booting from Windows, then I just want to see the three options. How can I acheive this? What do I need to do and in what order? Thanks.
