About to remove Ubuntu partition - GRUB?

Nope, grub2 creates its config files in Ubuntu. You can boot up with a live CD / rescue disk to edit the grub files. Also you can do this in grub itself once its loaded - I've only done this under GRUB (1) but it was quicker than trying to prick around with a live cd.

Thats the one, probe. The live CD will actually pickup which partition has its config files and rebuild them on that partition.

Check your settings in /etc/default/grub
Ubuntu your only OS ? (seeing that grub did not find others and therefore by default did not display a grub menu.)
GRUB_HIDDEN_TIMEOUT=0
Deleting the # mark will hide the GRUB Menu.
If you only have one operating system in the computer you might not need to see the menu, and you may want the timer left on 0 seconds for fast booting.
Sometimes people install Ubuntu in a computer they share with others who would be frightened and confused if they saw a GRUB Menu. If that's the case you can install Ubuntu and delete this hash mark to hide the GRUB Menu. If you set the timer to 3 seconds or so then others won't see the GRUB Menu so it won't annoy them.
The computer will still boot quickly enough, but if you press the shift key within the three second time limit you can bring up your GRUB Menu and boot Ubuntu.
GRUB_HIDDEN_TIMEOUT_QUIET=true
When the menu is hidden, this hides the timer as well. Set it to false if you do want to display the timer.
GRUB_TIMEOUT="10"
This number sets the number of seconds we want GRUB to wait before automatically booting the default boot entry, unless any key is pressed to cancel the count-down timer.
We can change this number to a smaller number of seconds if we want our computer to boot a little faster.
We can set this number to a higher number of seconds if we want more time to hit a key or decide what operating system we might want to boot.
We can change this number to -1 if we want to keep the countdown timer on hold and have GRUB wait forever or until we come back and tell GRUB what we want.

Do you have any versions of Linux installed after 11.04. I installed Ubuntu Server last and update-grub do nothing in Ubuntu Desktop (10.04).

Just thought that your GRUB_HIDDEN_TIMEOUT=0 may be set to a higher value causing the delay in the boot loader.
does your grub reference the partition explicitly or does it reference the UUID?
your grub is still probably pointing to the old place where your ubuntu was installed. change the grub entry to point to the new partition and you should be alright.

i think my advise above is relevant for original grub
grub2 has a line similar to set root=(hd1,5). That has to point to the partition where you have moved your install. if you haven't changed the entry since you moved your partition then it won't load.
