How do you change the default Grub boot option in Ubuntu 14.04? This has been asked and answered for older versions, but these solutions no longer seem to work for 14.04.
Specifically, the version of Grub used in 14.04 now has two screens. The first screen lists:
Ubuntu (default) Ubuntu advanced memory test memory test (other options)
And all the other actual kernel options are hidden under the "Ubuntu advanced" sub-menu.
I installed 14.04 server, but for some reason, it's using the generic-kernel. Unfortunately, the option to use the server kernel is listed under the "Ubuntu advanced" menu, and the
GRUB_DEFAULT index in
/etc/default/grub doesn't effect or select from those.
I tested this by changing the GRUB_DEFAULT to 4, corresponding to the 5th option under the "Ubuntu advanced" grub menu, but it still booted using the "Ubuntu (default)" generic kernel. How do I fix this?
