Where does bitdefender not scan?

I recently had a bad experience with a virus to where I hard reset my PC. After running several virus scans (full system) it has come up with nothing. I don't think that there is any virus on my PC anymore however I want to be really safe. I am not sure if my harddrive was reset or if there could be a virus on my recovery partition leading me to ask - is there anything that bitdefender does not scan? Will it scan my rootkit or recover partitions? I have also ran virus scans with Malwarebytes to which there was nothing detected.

Any help is appreciated!
