Moving bootloaader from MBR to ubuntu root partitiion

[Trey Sizemore]

I have recently installed Ubuntu 10.10 on a machine with 3 SATA drives.
Ubuntu was installed on /dev/sda with the root partition being sda1.

I did not see an option when installing for choosing where to install
the bootloader, so it installed on and overwrote my existing MBR where I
had a 3rd party boot manager for multiple OSes.

How can I re-install Ubuntu's bootloader to /dev/sda1 so I can
re-install the 3rd party bootloader and launch each desired OS?

I tried using grub-install but get:

trey at ubuntu-desktop:~$ sudo grub-install /dev/sda1
[sudo] password for trey: 
/usr/sbin/grub-setup: warn: Attempting to install GRUB to a partition
instead of the MBR.  This is a BAD idea..
/usr/sbin/grub-setup: warn: Embedding is not possible.  GRUB can only be
installed in this setup by using blocklists.  However, blocklists are
UNRELIABLE and their use is discouraged..
/usr/sbin/grub-setup: error: if you really want blocklists, use --force.

Thanks!
