How can I get my old bootloader back?

Question

I installed something and now I have bootloader from Debian.

It's not my screenshot!!

I have Ubuntu 12.04 and Windows 7.

->Ubuntu 12.04 ->Ubuntu 12.04 (recovery) ->Previous versions... ->Something with memory ->Something with memory ->Windows 7

When I chose Ubuntu, it will freeze and I have to restart the computer. So I have to wait 2 seconds, go down to windows and then up to ubuntu and press enter. That's working ... but it's .... not good....

So, please how can I uninstall this version to get the standart grub loader?

Or this?
