How do I return my boot option menu?

I had Windows 7 & Backtrack installed and when I would turn my laptop on, it would have a dual boot ubuntu manager where I would select booting into Windows 7 or Backtrack.

I deleted Windows 7 and reinstalled that operating system.
I'm guessing that during the Windows 7 installation it "repaired" the "bootmgr."

So now it just boots into Windows 7 without asking me if I want to boot into Backtrack.
The parition for Backtrack is still intacted. I just have no way of booting into it now.

Is there any possible way to fix the bootmgr back to the way it was without having to reinstall Backtrack?

There's no such thing as 'boot repair'. You need to re-apply grub to the harddisk. Easiest way to do that is with a Live CD. Pick any, it doesn't matter which.

You won't be able to do this from a UI so don't bother. All you (should) want is a command line under Linux and a mount point where you've mounted your original root device. From there, re-apply grub and/or lilo. From memory, with lilo it's running "lilo -C /etc/lilo.conf' command and for grub it's "grub2-mkconfig -o /boot/grub/grub.cfg" assuming that's where you put your config file. Note that you might have to update the config file such that it refers to the position of the kernel binary according to how things are mounted right now. So if your kernel file used to be /boot/kernel but your root is currently mounted as /mnt/root then the kernel file should be specified in the config file as /mnt/root/boot/kernel (similar logic probably needs to be applied to the location of the config file you're providing to grub/lilo)
