System Recycling

A friend of mine broke my Windows Xp Home Edition disk and I have no way of making a boot disk because the only computer I have access to is my sisters laptop, which does not have a floppy drive. I was wondering if there was anyway to make a new windows xp disk or if there was anyway to make a cd boot disk rather than a floppy. My computer has been down for a few weeks now and its driving me insane. I've looked at several different websites and found no help. Any suggestions please??
