Anyone able to rate Ubuntu 7.04 with dual-booting?

I've never had any problems with dualbooting. 7.04 should work fine. Like the others have said - if you play around too much then you'll screw stuff up. But that's only a problem for people like me who reinstall their OS every few months or make weird/major changes. Install Vista and then Ubuntu overtop of that and it should work great.

Microsoft products have an annoying tendency to delete the GRUB boot loader, so be careful with that...
