Many thanks for the fast reply.

Sorry for nudging about it - I just want to make it clear for myself:
You are saying that it is possible to reformat only the 'bad' partition - namely the partition with a bad OSx86 installation. As that partition will be in HSF (or HFS don't recall) format for Mac, will it be an easy process for Vista's NTFS? Will it be a straightforward formatting? or just one with few twists? in that case, is there a guide for that? I'm not asking that out of panic, just want to be prepared for everything.

And about chameleon (I guess I didn't find it because of bad spelling) - I saw it's a Mac program. So it means I first install the iATKOS DVD regualrly, and once it is installed I run Chameleon from Leopard? The bootloader managing is done through OSX?
And is it really that straightforward for dual booting? I hope it keeps Vista as the default one...

Thanks again,

Josh.
