I'm not sure it's call master boot or not. blush.gif

This is the story:

Notebook type: Acer TravelMate 6291
OS: Windows Vista Home Premium OEM

I make a 10GB partition for Ubuntu and installed.
Every startup there is a OS selection for me to choose either Ubuntu or Vista.

Now I want to restore it back to factory setting,
but I only can restore Vista partition with the Acer Recovery Disc that I create it at the very 1st day I bought this notebook. doh.gif

Any expert please let me know how to restore back to factory setting?
