It appears that Dell Local Datasafe Backup actually corrupts the grubloader every time you use Windows. A number of posts around the web pointed to uninstalling Dell Local Datasafe Backup and Dell Online Datasafe Backup - this solved the problem for me. To get into Windows once it fails, however, you need to repair Grub using an Ubuntu LiveCD. See this post for instructions:
