I have installed Ubuntu 12.0 alongside Windows 7. When I boot up and the select screen comes up the up/down selector buttons become inoperable and Ubuntu is automatically selected.

The boot up screen is called GRUB. Boot Ubuntu and try the following from a Terminal.

  1. Select the Linux kernels you want to be displayed by leaving only the kernel files in the /boot folder.

    cd /boot

    sudo mkdir old_kernels

    sudo mv *undesired_kernel* old_kernels [e.g. sudo mv 0-26 old_kernels]

  2. Modify the grub option editing

    sudo gedit /etc/default/grub

  3. sudo update-grub
