Windows expert needed...boot.ini has been deleted

So like a month ago, I deleted boot.ini
Don’t ask why, I don’t remember. I found it randomly and deleted it because it seemed out of place.

Anyways, now I want to reformat my hard drive, but I can’t since my computer won’t read my windows XP disc from the rom. I hit f12, and select boot from cd-Rom but i get an error message along the lines of drive not found ress f1 to restart or f2 to go to setup. I don’t have a flappy drive either.

Any ideas?
