I clone the system from time to time to make sure I have a functioning image. My existing backup was 4 months old (taken before I upgraded from lucid to precise), so it was time.
[BTW, I was reminded NOT to use a USB 2.0 drive (I have a n HD dock) as the target for clonezilla--takes twice as long--but I didn't feel like opening the case to hook up my spare drive and I didn't have an eSATA cable--doesn't pay to be lazy.]
Anyway, after cloning, I rebooted and followed darkod's instructions:
sudo apt-get remove --purge grub grub-pc grub-common
sudo apt-get install grub-pc
sudo grub-install /dev/sda
Went smoothly, and rebooted. All the noise I was getting at startup went away--lots of messages about VMWARE (which I do not use) and something about the SCO Timer (or something). Now it just boots..takes me from the Ubuntu logo screen to the password screen to my desktop. shows I'm now on kernmel version 3.2.0-35...so this is now done.
Thanks you all!
