Grub probleme

Résolu
Bonjour,

Hier J'ai fait des mises à jour sur ubuntu . Aujourd hui j'allume mon pc et surprise il ne m'affiche plus mon XP au démarage. Comment dois je faire pour repouvoir booter sur windows?

Merci d'avance.

Ps: je suis pas très fort sur tout ce qui touche à linux.
Configuration: Linux
Firefox 2.0.0.11
