Hello

  • What were the changes made before the problem occurred?
  • What happens when you start you computer?
  • Are you able to boot to the desktop?
  • You receive an error message?
  • If your friend has installed Windows 7 ultimate or just fixed the crash problem - was - it own installation\custom?
  • What version of Windows are you using?
  • When you say "windows home premium" are you referring to Windows Vista or Windows 7?

If you are able to boot to the desktop, you can check the version of Windows.

Response with more information.
