Don't reinstall grub...

1. boot windows and confirm that \ubuntu\disks\root.disk exists. Back it up.
2. if it isn't there, look for a hidden C:\FOUND.000 folder and see if windows placed it there (it could be called something different so look for root.disk or a file with a generic name e.g. chkxxxx.chk of the same size.
3. run chkdsk (My computer, right click on 'drive' (that contains \ubuntu), Properties, Tools, Check disk for errors, fix automatically.
4. If that doesn't fix it, boot the live CD, mount the partition that contains the root.disk, and run fsck on it. e.g. if it's /dev/sda2:
sudo mkdir /media/win
sudo mount /dev/sda2 /media/win
sudo fsck /media/win/ubuntu/disks/root.disk

Post back if you have any questions on the above or refer to the Wubi Guide: https://wiki.ubuntu.com/WubiGuide

You can also try and recover data from the root.disk from windows using this tool: http://ext2read.blogspot.com/
