You mention that you are using different partition managers on same disk time and again. This is a problem in itself. No two partition managers work the same way and neither work the existing partition same way. You are bound to get wierd results, some times you will even need to repartation it.

I cant recall a partation manager it was based on linux and it can be written to a botable CD. I have it I will let you know later.

Can I ask you a question, whats is that you want to achieve by hopping mutiple distros so frequently. If you can explain clearly what is that you specificaly need from a distro, may be some of us can be of good help to you.
