Have you tried succesfully to update?

It was really a mess to do the Tri-Boot in a single Hard Drive but I finally could

However I don't want to spend time in an update if I know it will fail or it success is not sure. That would make me reinstall the MBR many times to get Tri-Boot again.

Today I (stupidly) tried to install the Adobe Master Collection CS4 in my ToshiMac and I (sweetly) got my first Kernel Panic <3

In fact, I'm not sure if it was that the programs were too heavy or if it was a small coup that gave my laptop while it was installing. During the long installation process I had to move my computer to another place (from my house to the house of another friend), so I closed the lid and when I reached the house he found the Kernel Panic. I'm not sure and I would like to reinstall to confirm (:

When I rebooted I could boot perfectly into Leopard again, however there were missing parts of the CS4 Suite and the .dmg file that i decompressed before from those parts dissapeared o_O
Although, some programas were installed (like Bridge, Dreamweaver, SoundBooth) and were working perfectly.
I think that Mac creates something like a restore point and after a Kernel Panic it goes back to the last restore point created.
The thing is those files were saved in a NTFS partition which is the Windows XP partition and now I can't recover them
T_T

I tried with many programs to recover lost or deleted information but I failed to restore them.
The only solution: download them all again

Anyone of you have experiences with installing programs? If so, which ine did you installed and how did they worked?
Again, just wanting to compare experiences :P

Cheers!
