I have Ubuntu 10.04 installed with Grub (legacy?) and an external

Both with Grub in the mbr.
I wish to remove the external drive with 11.04 as machine will not
boot with this drive disconnected,
but there is no 11.04 entry for me to edit in menu.1st file.

Will installing Grub2 on my original 10.04 give me a file that I
can remove the 11.04 entry from Grub?
or will it present me with problems? I have checked out the
archives, but obviously am not asking the right questions
on searching, as I can't find anything relevant there.
Many thanks in advance.
Take care

the last grub which you install (no matter if 2 or 1) into the MBR depends on the /boot/grub folder _from_ where you install.

=> re-install grub with all steps from your internal installation - while the external HD is connected also.
(update-grub, grub-install /dev/<bootdevice>)
Then you will be able to boot all found OS'es as far as they are connected.
