I recently installed Ubuntu 10.10 on my desktop which also have windows xp installed. After the installation I could boot to both Ubuntu and Windows. I then installed some updates from the update manager in Ubuntu 10.10 and after this the windows option in the grub boot menu is gone.
I am newbie so I don't know what is wrong and I am hoping someone can help with this issue,
The boot_info_script055.sh returned the following result
Boot Info Script 0.55 dated February 15th, 2010
