Installed Ubuntu twice, and would like delete one of them

Good day. I have installed Ubuntu 9.04 twice. I want to use first one(/dev/sda1), so I have to delete second one.
But it seems, system read /boot/grub/menu.lst file from OS that was installed second.
How can I properly delete second installed Ubuntu?

Thanks for attention.

i think you need to format the /dev/sda6 and restore the grub on /dev/sda1.. may be the grub is written to your mbr.. so what you have to do is just format the second ubuntu..

What puzzled me is where ever you installed GRUB of the second installation it should have both installation in its menu.lst
If you started UBUNTU which choices are presented which ?

Using the option presented to you when UBUNTU is booting and knowing that UBUNTU is using UUID to boot we can determine which UBUNTu is booting
The next command will give you the UUID
ls -l(L lower case) /dev/disk/by-uuid
than you know for certain with UBUNTU is booting
