The spinning globe means that you are connecting to the Internet Recovery system, and takes a long time to get there because you are connecting remotely to Apple's servers - and not to anything on your hard drive. You will still see a menu allowing you to reinstall OS X, and some other choices, including Disk Utility. When you get to the menus, go ahead and check Disk Utility, where you can see your hard drive. I suspect that you WON'T see it at all, which means that your hard drive has failed.
Ah, but you also will lose everything that is not backed up somewhere else.
If you have been using iCloud, or some other web backup service, then you still have that. If you have all of your drive backed up on an external drive, this is the time when you will be glad that you did that!
And, Apple made that easy for you with Time Machine...
OK, I read your last post, and I see that unfortunately you have no backup... That will be tough.
Let your MBPro continue to boot to the Internet Recovery, and try the Disk Utility. Maybe you will be quite lucky, and you simply need to run the First Aid.
(note - external hard drives are not expensive. Time Machine makes backup automatic - you don't have to think about doing backups. All you need is to plug the drive in to your Mac, and Time Machine takes it from there.
lesson learned? )
and sorry for having loads of questions!
