Dual Booting Ubuntu 12.04 and Windows 7

Question

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.

Answer 1

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
