Windows 10 does not start anymore because of c hard disk. What can I do?

I've set the ssd c hard disk to no longer provide storage space except for the operating system. Configuring meant that was me or something. After I restarted my laptop, Windows stops working. See pictures. I can't reset it, not restore it. Nothing at all. The laptop is not even 3 days old. I'm totally desperate.

I would put in your place the PC or put on new, was not good what you did.

How do I do that? The laptop did not come with a Windows CD.

You can simply download Windows 10 from Microsoft and copy it to a USB stick. https://www.microsoft.com/.../windows10

From the stick you start then your laptop. Incidentally, your Windows license is linked to the laptop. If you are reinstalling Windows, it should automatically activate itself because the Microsoft servers recognize your laptop.

How should I do that? I can't get in…

Many manufacturers offer a reset option. This is a button to press at startup. Which make is this?

Acer

Hold down Alt + F10 when starting.
