Let us know what/how you are updating when that happens. What version of 
Ubuntu were you having last and what version are you updating to.

I guess the update involves updating the grub-legacy to grub2 and you 
did not follow through to setting grub2 properly.

Michael, if you have been following my recent post, and if you have a 
grub2 cd, you can boot into your ubuntu partition. (Do method *2* of my 
post). After booting up, you need to install grub-pc by "sudo apt-get 
install grub2" in a terminal and follow all the steps through with 
additional instructions. You must set your grub to sda (or mbr). Please 
go through the recent posts and let me know if you need to have a grub2 
iso sent to you.

If you think you might have a problem doing this, I suggest that you do 
a fresh install of your Ubuntu. Some of us here do a fresh install 
(including me) for any new final versions of Ubuntu.

Let us know if you need that grub2 iso.
