I allowed Ubunto to upgrade my software and when it restarted I can no long start up Ubunto. I can still boot Windows but when I try to boot linux it comes up with a grub entry line.

The OS is called UBUNTU (pronounce OO-BOON-TOO), not ubunto.

I suggest you boot to liveCD, chroot to the installed OS and run:

sudo update-grub

But I see any Linux partition. The "Linux Swap/Solaris" contain virtual memory, not system.
Please provide correct partition table: https://answers.launchpad.net/grub/+faqs
