you tried to restore with windows cd probably grub was removed. You need to reinstall it.

Yes that problem is common when you remove OSs so you will have to boot from a live CD and re install Grub from there.
Good luck to you!

Were you using the Backtrack bootloader to boot all three systems? If that was the case and you deleted the Backtrack partition, most of the required boot files are gone.

If you were using Grub2 from Mint that would not be the problem. It's much easier to reinstall Grub2 than to try to configure some windows third party bootloader to boot your systems. Check the instructions at the site below:

You might find that downloading and burning a "SuperGRUB2" boot cd / rescue cd might be helpful in your situation, I have found it to be a useful tool myself multiple times. It can be found here:
http://www.supergrubdisk.org/super-grub2-disk/

(You would of course need to use another PC, or to boot a live CD on your PC that is not booting from the HD in order to be able to do that.)

(Having a burned SuperGRUB2 CD might let you boot back into the HD that is not booting (boot into Linux OR Windows), without even needing to install GRUB to the HD. But if you do want to, I believe you have that option with it also.)

Good luck!

I use SuperGrub as well. I set up a small separate partition and install grub there. It takes up less than 15 Mb. I use SuperGrub to install grub on the MBR to point to that partition to boot to. Then I edit menu.lst in that small partition to chainload to the different partitions that I want to go to. When installing new OS' I have them write their grub boot to /root. I can then add OS's and delete OS's without touching the MBR. I just have to edit menu.lst in that small boot partition. If you delete an OS you don't even have to edit that file until you want to. Just don't ask the computer to boot to an OS that is not there any longer.

When all else fails go Old School , crude but effective.

Burning a Grub Legacy Boot CD and using the Command Prompt Will get you to the bare minumum. Use the root command,kernel command maybe with root= and also the initrd command and you can't go wrong. Then type (boot) and press "enter". This will allow you to boot all of your installed O.Ss and then you can address having a Grub partition or whatever later when it is not an emergency.
