I upgraded Ubuntu on my laptop and I have to use the old boot link for it to work. How can I make my laptop automatically use the working boot-up? When I use the new GRUB entry the screen goes blank and the computer seems to hang.

you have to know the number of the working item

For example: The First line has number 0 , the second 1 etc.


sudo gedit /etc/default/grub

And change the line GRUB_DEFAULT=0 to


now execute sudo update-grub

Everything should work now.
