How to add a Windows 7 partition to grub2's list of available OS?

Question

I'm not sure how it happened, but I lost the "windows 7" entry from my Grub2 screen after updating ubuntu.

How can I add it ? I knew how to do it in grub legacy, not in grub 2

Solution 1

You could try installing grub-pc tools to automatically detect all available operating systems

sudo aptitude install grub-pc

and then update grub2 for your next restart

sudo update-grub2

if Windows is correctly installed it should now be added to grub.cfg

Solution 2

Doesn't seem to find windows ... arg maybe my partition is corrupted in some way :'(

In that case I'd backup everything from the Windows partition as soon as possible and reinstall. Can you browse the windows partition when logged in Ubuntu?
