Dire need of help, ive created a monster.

So ill just start at the beginning. I was having issues with my computer so i system restored. Turns out i restored to about 4 years ago on a backup restore point. Well after it completed my computer was botched. Couldnt connect, couldnt update drivers or troubleshoot. So i made a terrible choice and i set my recovery partition to active to try and fsctory reset through my recivery partition, now i can only boot to a black screen saying bootmgr is missing, control alt del to restart...help me fix this please... Im on a win 7 desktop.

I do not have a recovery disc. That would be an obvious fix. My computer came with windows on it, which is why i was trying to boot it on the recovery partition to factory reset it that way.
