Carlton,

Doing  the sudo update=grub would have replaced the MBR on sda unless you specified otherwise.  That should not be a problem unless you actually WANT to be unplugging and plugging drive to change what boots.  The Win7 loader it found for sdb is probably an artifact of how it was formatted.  It should not work if it is a data drive as you say.  It is possible to remove that entry from the grub menu but you need to do it correctly.

I am not sure you are up to this but here is link to a discussion of doing this.

If you are not sure of yourself doing this, ypu could bring your system to an installfest and I can do it for you.

I just upgraded to 11.04 by disconnecting sda and sdb. I then installed
11.04. I then reconnect all the drives

After install I did a sudo update-grub. It displayed the following

Generating grub.cfg ...

I have no idea why 2 Windows.

Then ran fdisk -l. It displayed the following

Now when I boot up it shows the grub menu, and lists all the choices,
but when the Windows sda1 is picked it reboots. When sdb1 is picked it
says I have a windows error.

I beleive I have corrupted or destroyed the Windows MBR or Boot Record.
I have attempted to fix it using the Windows disk but still does not
work.

Any help would be appreciated.
