Q: Prohibited sign when trying to boot os x after bootcamp install

HI everyone, so I was all chuffed with myself after I got windows 10 installed on my new machine via bootcamp. But now it seems I can't actually boot os x as I get the prohibited symbol. What should I do?! Thanks in advance

First, boot from the Recovery HD and determine if you still have an OS X partition. You may have unwittingly destroyed it when formatting the Windows volume. If you do still have one then do the following:
