ruined my grub/ubuntu 10.04
 

I updated and rebooted. Not paying close enough attention I booted into my old HDD and updated again. Now I have a 314 gig file system that does not appear on my Boot Screen. I booted into the 40 gig that contains my old 10.04 and I did an Update Grub but to no avail. I can access the files of course, so it isn't the end of the world but I really want to et the new install on my new 320 gig back as my sd1 drive, any hope?

Try the section called booting Linux in this article:

I did but no help.

Try booting from the Ubuntu 10.04 live CD and restore grub2 to the MBR of whatever drive you want to boot from:
https://help.ubuntu.com/community/Gr...ing%20GRUB%202
Just use the first method listed there. Then boot into your Ubuntu and run:
Running sudo update-grub from the Ubuntu on the 40GB system should have picked up the other Ubuntu though. I am not sure why it did not.
Also, make sure that hard drive you want to boot from is selected as the first boot device in the computer's BIOS.

NOTE: If you have 2 Ubuntu installs on your system, and both of them have their grub set to control the MBR, then each time there is a kernel update, each version of Ubuntu will attempt to use it's grub to update the MBR.

That worked, thank you.

I could of sworn I put that in my tutorial. I guess not. I'll have to add that...... oops:o

Your tutorial has stuff about grub-legacy. Starting with version 9.10, Ubuntu now uses grub2. The procedures for updating and reinstalling grub2 are a bit different.
