Ok, I know I'm late but here's how I got it damaged first like OP & then got it working again in first attempt (it was also the first time I tried reinstalling Grub). I did it all in VMware on a 40GB virtual HDD.
First, I created partitions that resembled the partition scheme of OP (sda2 being active).
Code:
Disk /dev/sda: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0007cd0c
Device Boot Start End Blocks Id System
/dev/sda1 1 877 7044471 83 Linux
/dev/sda2 * 878 1694 6562552+ 83 Linux
/dev/sda3 1695 2562 6972210 83 Linux
/dev/sda4 2563 5221 21358417+ 5 Extended
/dev/sda5 2563 4955 19221741 83 Linux
/dev/sda6 4956 5221 2136613+ 82 Linux swap / Solaris
Then I installed Lucid on sda1, then maverick on sda2 (yes, I downloaded it last night!). So far so good! Then as soon as I installed BackTrack4 on sda3 it became the only bootable OS with others listed in Grub but not bootable - just like OP's tragedy! (well.... well-planned sabotage in my case
)
Here's the output of boot info script at that time:
Code:

Then I booted off Lucid LiveCD and mounted sda1 on /mnt like this:
Code:
sudo mount /dev/sda1 /mnt
After that I installed Grub2 like this:
Code:
sudo grub-install --root-directory=/mnt/ /dev/sda
It gave me a message that Grub2 installed without errors, then I rebooted. On reboot it booted itself into Lucid where I ran update-grubWhile updating it displayed the other two versions it found & listed. I rebooted again & everything is cool now! I can boot any of the three OS I wish. Here's the output of boot info script as of now:
Code:

@joshmuffin,
Based on above experiment, here's what I can suggest:
- Get/burn a Lucid LiveCD. Reinstall Grub2 mounting only sda1 just like I did. Although I don't really know whether it would install the missing /boot/grub/core.img file or not. But if it did, then Lucid should boot normally where you can run 'update-grub'.
- If above doesn't get your Lucid on sda1 working again then reinstall entire Lucid OS on the same partition (sda1). This should automatically fix everything else.
You said you don't have any LiveCD. I'd say "get one" since you are going to need one anyway. If burning a CD is a problem, here's a quick workaround:
- Download Lucid Desktop (LiveCD) iso.
- Install Virtualbox on your running OS.
- Load the iso in VirtualBox as a CD & booting off it, create a Live USB stick (the one you currently have mint9 upon) from system>administration>startup disk creator.
- Use that Live USB stick in place of CD.
END NOTE:
Now that I've finished suggesting whatever I could, I'll try to focus upon what oldfred has suggested.
I'm sure it is much more promising & mature set of instructions, but to be perfectly honest, it is so high above my head that I'll at least once consider commiting suicide if someone told me to go through all of it right now.
Just kidding
