I am at a loss as to what is going on with my ubuntu server install. The server was running Ubuntu 11.10 Server and was working fine. I upgrraded to 12.04 and that hosed the Kernel, to get it to boot I had to delete the new kernel and revert to 2.6.32-42-server which worked for a few days till I had to upgrade again.
After the upgrade the machine would not boot.
I reverted to 2.6.32-41 and it also worked for a few days and I got another message to upgrade which I did and now the server is dead again ... I iam able to boot if I chose 2.6.32-40, but it is getting tiring to have to do this every few days... I am witts end, what to do what to do??

Thanks in advance for the help

I believe this will get you going
In a terminal, run sudo update-grub
Then, type grep menuentry /boot/grub2/grub.cfg
Counting from 0, find the number of the line containing the 2.6 entry you want.
Set that as default in /etc/default/grub and run sudo update-grub again.

There is not enough information in this. How far does it get in the boot process? Did you look into the log files? What are your hardware specs?
