You need to determine if the disk is bad or if it is simply corrupted and needs a startup repair.

Have you run diagnostics?
Tap the ESC key after powering on. . Tap it once a second after you see the LEDs on the keyboard flash. When you see the startup menu, press F2 to run diagnostics. If a component fails during the UEFI test then Click here to check warranty and Click here for world-wide contact info

If you can pass the memory and disk test then you need to do a startup repair.

To do a startup repair you need to boot into windows recovery mode. First read this article about safe mode.
Skip down to 'Enter safe mode from outside windows'.  If F11 does not get you into system recovery then try turning the power on and off three or more times in a row.
When you get to advanced options select 'Startup Repair'

If the startup repair fails then try the restore point.

This video describes how to use a restore point. Ignore that it shows windows working. Clicking on "System restore" will bring up the list of restore points similar to what is in the below video.
