Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I bought a Windows 8 computer. I then installed Ubuntu-Windows-Installer-12.10. When I boot the system, I see a screen with two options to choose from:

  1. Windows8 (which works fine and I can start Windows with no problem.)
  2. Ubuntu (which does not work. I get an error message: Windows failed to start. A recent hardware or software change might be the cause.)

What is wrong and how can I fix this? I really appreciate your help.
