The boot up screen is called GRUB. Boot Ubuntu and try the following from a Terminal.
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
]Modify the grub option editing
sudo gedit /etc/default/grub
sudo update-grub
