Running Dell Inspiron 15r notebook with Windows 7 Pro and 11.10 Ubuntu (also have Windows CR). All worked fine until attempted upgrade to 12.04 system which 'locked'.

Via Windows, uninstalled and reinstalled Ubuntu 12.04. Windows install part went okay, but when rebooted to continue installation in 12.04 was only able to boot into grub (i.e., grub> prompt).

Have tried to uninstall and reinstall (via Windows). Also, ran Boot-Repair CD -- no change.

Here is the link to the Boot-Repair's Boot Info Summary:

  1. Run Boot-Repair's "Recommended repair". This will open a file browser that will let you access and backup your Ubuntu files if necessary.
  2. Via Windows "Add/remove programs", remove your current Ubuntu
  3. Reinstall Ubuntu OUTSIDE WIndows (without using Wubi), by following: https://help.ubuntu.com/community/GraphicalInstall
