The Sims 2 lost disc

[S_Northover8]

Hello, 

I have completely lost the disc to my Sims 2. I cant even reinstall it onto my PC now that it is gone let alone play it. I've lost Disc 1... It was my brothers game but when he grew older he passed it down to me..

Is there anything I can do to reinstall it and then install one of the bonus packs I have. 

Thanks
