I'll be careful. I'm still on XP and if I've got enough power I may try to run most of my Windows stuff in vmware and never go to Win 7. We'll see. I may need to some back and ask some questions about grub and dual-boot anyway as I expect it was my grub install that corrupted the existing Windows installation but I don't know yet. Again, thanks!
