Help with Dual Boot systems

Hello!

True Image v.11
Single HD
2 x 32gb Partitions.

Partition 1 XP Home
Partition 2 Win7 64bit.

I already have a secure zone created on another drive through XP.

What is the best to have two images of the system drives, and subsequent incremental backups of the two operating systems, without overlaps or deletions.

If i were to ever need to boot using the boot manager acronis, I would also like to be able to choose which OS i need restored.

Thanks a ton!

Regards,
Sidhu
