Not getting boot loader screen to choose between Ubuntu and Windows 7

I was using 12.04 beta. I was asked by update manager to make required updates, which I did. I shut down my PC that night and the next day I was not able to boot into the graphical interface. After some attempts to fix it, I decided to remove beta and do a fresh install of Ubuntu 12.04.

I went into Windows 7, and in the disk management tool I deleted the Linux volume and swap volume. Then when I rebooted I was stuck with a grub rescue screen. I was not able to boot into Windows 7. I used boot-repair. I clicked on recommended repair and voila!! I got my Windows 7 back. So I decided to install Ubuntu 12.04 again. I did and when I rebooted I was not asked for OS options and was directly taken to Windows 7. I tried using this help wiki page to reinstall GRUB, but I am still not able to go into Ubuntu or get a boot loader screen. I guess my GRUB was messed up pretty badly when I deleted the Linux partition in the first place.

What should I do now?

Moving comments to an answer:

Grub2 is installed to sdc not sda. if you want it to magically find, it needs to be on the drive your motherboard defaults to. This in most cases is sda.

Under typical circumstances when installing grub2 it should be on /dev/sda.

You can do this from a liveCD or using the boot repair disks you found. I tend to favor a liveCD because I control exactly what is going on, but it lacks an easy-button.
