Vista - Partitioning software incompatibilities

I recently enountered siginificant incompatibilities using Partition Magic in Windows 2000 creating a dual boot Windows 2000/Ubuntu Linux system.

I realize that PM must not be used in Vista or Windows 7.

I am planning on having two Windows 7 systems as follows:

1. Dual boot Windows XP Pro/Windows 7 Pro.
2. Dual boot Windows Vista Home Premium/Windows 7 Home.

For the XP system, I could format the partitionss using Partition Magic, run from XP, but if I later wish to add a Linux partition. I'd likely have the same problem I desctibed in the link supra.

For the Vista system, I could format the partitions using Acronis Disk Director 10, run from Vista. Again, this might be complicated by using Disk Director, I do not yet know.

So, what partitioning software is required for the following cases:

1. Dual boot XP/Windows 7
2. Dual boot Vista/Windows 7
3. Triple-boot XP/Windows 7/Ubuntu Linux.
4. Triple boot Vista/Windows 7/Ubuntu Linux

I am asking this same question in a Windows 7 and in an Ubuntu forum.
