Let me try to figure out what you did.
So you have windows on SDA1 & 2
Then installed Ubuntu was on sda3? With /boot on sda3
Then you added SDA4 and put ubuntu on SDA6 with a new /boot on sda6, with
Swap on 5 &7?
Correct??

Hi every body.
I have not made any changes yet because some thing aren't clear yet.
I have
/dev/sda1 ntfs 48gb boot
/dev/sda2 ntfs 98gb
/dev/sda3 ext3 20gb
/dev/sda4 extended
/dev/sda6 ext3 120gb /
/dev/sda7 linux-swap 5gb
/dev/sda5 linux-swap 5gb
So when i boot the system the MBR on sda1 looks on sda3 for the grub
menu.list
I want it so that when I boot the system the MBR on sda1 looks on sda6 for
the grub menu.list.
I have rub gparted and and startupmanager, but they do not seem to have the
ability to make this change.
Any ideas as to how to do this?

No, don't do that.
You need to keep the partition and menu.lst matching.
Copying like you propose is more for experience people that totally
understand how grub works.
I have been burned by it when I started playing with grub, and then its,
a get the install CD run from the CD and fix the mess.
If you want to boot from your original, printout your new menu.lst, know
what 4 lines boot the new OS.
Then use partition manager and get it to boot from your old Partition.
When you can boot from your Old Partition use gedit to type the section
from your printed menu.lst that does the boot for that.
sudo gedit /boot/grub/menu.lst
copy the piece that boots the original part, to the second position and
then edit the new entry to match your new partition boot, as per printed
menu.lst
This is the safest way if you do not totally understand grub.
