(Wubi) Ubuntu missing on dual boot

I have dual boot windows 7 and ubuntu 12.04. Now ubuntu is missing after windows checked /tmp for errors. I only get windows and gnu grub options upon reboot. I looked in installation folder and root.disk was at 0 kb. Can I access my data throught windows? Next, I ran a liveusb and boot-repair and still only getting gnu grub. I am attaching bootscript output. How do I restore my normal ubuntu and restore files and folders? Mainly interested in recovering the personal files and folders.
