Default to Older Kernel (Hidden in Submenu)

[rickatnight11]

Because my RocketRaid 2680 drivers won't run on anything newer than 2.6.38-8, I haven't been able to use newer kernels. The only way to boot from this kernel version, however, is to manually select the Previous Versions menu from Grub and select the kernel from there. This means that I'm screwed, if I need to reboot the server remotely.

How can I have grub automatically boot from 2.6.38-8 (after the 5-second timeout)?

I'm presuming you are asking how to set an entry in a submenu as the default?

I wrote a guide about how to use the new submenu structure in Grub 1.99:

Fantastic guide. All I had to do was update /etc/default/grub with:

...
GRUB_DEFAULT="Previous Linux versions>Ubuntu, with Linux 2.6.38-8-server"
...

...and run sudo update-grub to commit the changes. Thanks so much for the help!

The Grub 1.99 submenu feature is going to give users a bit of a problem until it's use becomes more commonplace.

I like the submenu structure, which makes things simple for users who want a 'clean' menu but don't want to get under the hood to tweak things. For the rest of us, we just have to do a bit of learning.

Please mark this SOLVED via the 'Thread Tools' link at the top right of the original post if you have no further issues.

Happy Ubuntu-ing !
