Laptop shut down during windows 10 upgrade?

Laptop shut down during windows 10 upgrade?

Added (1). I have a new Lenovo yoga 500, and I reupgraded my laptop to win10 after I refreshed my entire system once (I had some problems, nothin to do with my problem now)
but laptop turned off cause I used up my battery. Now it's stuck on the loading screen.

It's not frozen
Sometimes goes blank then back to the loading screen
A page pops up sometimes
The screen sometimes goes blue or green
I have a cursor that actually moves
It's shuts down and turns on properly
left it for 1 day and night.
Please help

Added (2). Yes, I know it's not a proper system yet and still has to report to the windows regularly, and I can get the current win 10 for free right now.

"used up battery" will spoil your upgrade. Now files are partial or scrambled. You will have to start over. Contact Micro$oft on how to.
You are aware that w10 is not a licensed operating system that is your property, like previous versions? It is now a service that you will subscribe to by paying on a periodic basis? And it reports activity back to Micro$oft regularly?
