Initially I have installed microsoft windows 7 Ultimate and Ubuntu 10 in my notebook. microsoft windows and ubuntu are located in different partitions on my hard drive. then I reinstall microsoft windows by formatting the partition and not format the ubuntu partition. question: How to reactivate ubuntu without having to reinstall the operating system ubuntu 10?

thanks, ade
