Ok so you used Wubi to install it. Wubi still has some issues. It is running some sort of virtualisation withing windows. more here: http://wubi-installer.org/faq.php

i suggest you do a propper dual boot instal. check the manual on how to do it.

[Rubi1200]

Installing Wubi can be problematic, especially since there have been recent GRUB related issues.

See here for more information:

Important Note to Wubi (Windows Ubuntu) Users: Grub Update results in "No Such Disk":
A late July 2010 Grub 2 update is causing a "no such disk" error for some users of WUBI, resulting in an unbootable system. If the system doesn't display the original Windows menu, the most likely cause of the failure is that Grub 2 was installed in the MBR and/or on the Windows partition. To correct this, restore the Windows bootloader using this link:
How to restore the Ubuntu/XP/Vista/7 bootloader (http://ubuntuforums.org/showthread.php?t=1014708)

Whether the failure is due to improper user selections or Grub 2's failure to recognize a Wubi install, it has been reported in the following bug and users can review it for status updates and recovery options when they become available:
https://bugs.launchpad.net/wubi/+bug/610898
http://ubuntuforums.org/showthread.php?t=1195275

If you can still boot into Windows, then consider moving the Ubuntu install to the drive:
http://ubuntuforums.org/showthread.php?t=1519354

If you are also having problems booting Windows, I suggest first reinstall the Windows bootloader and then take the necessary steps to make Ubuntu a more permanent install.

There is a problem with grub2 and lupin (used for wubi) that has got the wubildr out of sync with the latest version of grub.

So, basically, wubildr can't handle the commands in the grub.cfg menu and the computer reboots.

To fix from live CD:

sudo mkdir /media/win
sudo mount /dev/sda8 /media/win
sudo mount -o loop /media/win/ubuntu/disks/root.disk /mnt

Edit grub.cfg and delete everything above the first menuentry. Everything above

### BEGIN /etc/grub.d/10_lupin ###
menuentry "Ubuntu, Linux 2.6.32-25-generic" {

gksudo gedit /mnt/boot/grub/grub.cfg

save and reboot. Don't update grub-pc afterwards, run "sudo update-grub", or install/uninstall any kernels, or the problem will reoccur.

I'm not aware of a fix. So you can install a direct version of ubuntu. Or you can migrate your wubi install to a direct install. This will prevent the problem reoccurring and keep all your data/settings in tact.
