My bootloader Changed suddenly.

[Alahlavo]

Hello ,

Today I downloaded an Activation for Windows 7.

It requires a reboot.

When I rebooted suddenly I was in a "Grub Command prompt" apparently.

Just like this :

Important :

I downloaded Ubuntu couple days ago but I removed it.
I mean I had a boot loader with windows and ubuntu but I removed it.

My question is this :

How did it happened? , is this a Virus? and How can I go back to my previous bootloader when I would turn on my computer or reboot it and it would just go to Windows.

Thanks in advance.
