Re-installing GRUB / Windows

[Loïc Martin]

I would advise not relying on Dapper Install CD to reinstall grub, 
unless you want to edit manually /boot/grub/menu.lst, then run 
grub-install /dev/yourhd, because out of the two machines with XP I 
installed either Flight cd 4 or 5 onto, none got the Windows XP 
partition configured by grub for booting. Hoary install cd had no pb, 
though. I don't have the machines at hand, that's why I didn't file a 
bug, but maybe others have had similar experiences (oh, correction : you 
can try it, so you'll be the one filling the bug :D )
