Ubuntu – Cannot boot to Ubuntu, though installation was successful

dual-bootgrub2installationwindows

I installed Ubuntu 12.04 on an HP Pavilion H8-1228 computer via USB flash drive. Installation was a success. My computer still starts Windows, but there is no way to boot to Ubuntu.

I tried hitting F5 to display a boot menu. There is no "Ubuntu" option.

How can I boot into newly my installed Ubuntu system?

  • Usually when this happens it is because Ubuntu's installer didn't properly install the boot loader.

    Assuming you installed Ubuntu by booting from a live CD/DVD or USB flash drive (or from the alternate CD) and running the installer (that is, not from within Windows using Wubi), you can fix this problem by reinstalling GRUB2 to the Master Boot Record using one of these methods.
