[Ubuntu-BD] find out the ubuntu boot loader

[sazzad riyadh]

I was using windows xp and ubuntu 10.10 as dual boot. the windows xp was
set up in c drive and ubuntu 10.10 was set up in another drive ( I forget
the drive name). A few days ago I install windows 7 starter in my pc.
 After installing windows 7, I don't find the option to use ubuntu at the
time of starting pc. When I start pc directly windows 7 starts. But before
installing windows 7, there was option for ubuntu 10.10 and windows xp. How
can I find the option for ubuntu 10.10?

If anyone know the procedure please tell me.
