Re: 12.04 Upgrade - Raid Array Still Using Old Kernel & Grub
It looks to me like you have two installations, knowingly or not.
Look at the second image. One ubuntu entry is on top, and then the 3.2.0 kernel (the kernel from 12.04) is below the memory test entry, which is where grub2 puts other OSs found on the machine.
So, there is one ubuntu with 2.6.38 as principal, and another with 3.2.0 on /dev/sda3.
I think you should investigate this, but if you only want to make the 12.04 primary OS, simply boot the 3.2.0 entry below the memory test, and once booted execute in terminal:
sudo grub-install /dev/sda
That will make grub2 from 12.04 to install on the MBR of the disk and be the main one. So the 12.04 will become the default OS on top of the boot menu.
Darko.
