Repair Windows 7 Starter on netbook

Hello!

After repartitioning the hard drive of a Packard Bell Dot S and installing Ubuntu on it, Windows 7 Starter won't start anymore, but instead Startup Repair gets started. This cannot repair the problem.

I didn't mess up the partitions of Windows, but I can now select two Windows installs in GRUB. One is in Dutch and the other in English when Startup Repair starts.

How can I repair Windows 7 Starter without losing data/Ubuntu install?

Thanks!
