You may try this
https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows

Follow the text. You didn't said what version of ubuntu are you using
(to answer is it grub, grub legacy, grub2?).

The recheck option will probe your device map, but there's a warning
on the man page
http://linux.die.net/man/8/grub-install
I'll try it anyway if the rest fails.

Then do an sudo update-grub (or sudo update-grub2) on your linux (on
hdd). Or you may just try this before, as in now. :)

Worked for me
