I received Windows 10 Home as a DVD and would like to install it on my laptop, but it has no DVD input or something. Is there still a way to install it on the laptop or do I have to get an external drive?
Sure, that's called a USB drive.

You can use it to create your own installation medium.
You can create an installation medium on a USB stick. Microsoft offers a tool for this purpose: https://www.microsoft.com/.../windows10
There are external drives that you can connect to your computer via USB
THAT would definitely be preferable to a DVD.
