Q: Macbook air showing a file folder with a question mark upon start up

My mac book air shows a flashing file folder with a question mark in it.  When I hold down cmd and r I then get a screen with a globe and a clock that shows 24:00.  I have been told that I will need to reinstall the system software.  I do not have a back up created or a bootable version on a usb.  Can I download OSX on a windows based computer to create a bootable desk?

MacBook Air, OS X El Capitan (10.11.1)
