I have had a successful dual boot system between ubuntu and windows 7 for a while, using grub2 (or 1.98 to be precise).
I have recently updated Ubuntu to the 10.04 distribution through the update manager. It works. But now, every time I try to boot windows, my computer either restarts or it brings me back to the grub screen like nothing happened.
For reference:
Output of "sudo cfdisk" (NOTE: As you've probably guessed, the two main partitions are sda1 and sda3, for storage at least.):

If you need anything else that would potentially solve the problem, I'll be more than happy to provide it!
