Stupid Windows

Trying to install Windows 7 beside MacOS on my old Laptop for my brother, and it is being SO DAMN STUBBORN.  It just won’t boot from the DVD.  Which is understandable, as the interal drive only works when it wants to.  But I have an external, which I KNOW worked before, and its not working now.  I’m about ready to start pulling my hair out!!

Sigh.
