I faced similar issues with Dell's backup/restore software for windows 7, which I multiboot with Ubuntu.Still others had this issue with HP backup and recovery manager
The relevant bug is here - https://bugs.launchpad.net/debian/+source/grub2/+bug/441941
What is interesting is that Grub apparently doesnt have a problem, but Grub2 does.
I got rid of it simply by uninstalling any bundled software (Dell, HP, Sony, Lenovo) BEFORE installing Linux.
