Question I want to install windows on an already installed SSD in my system

[ChadderCheez]

Im wanting to change my boot drive from my HDD to my SSD as I have a replacement 2TB M.2 drive coming in the mail tomorrow. I dont have a flash drive or CD to burn to either. The SSD in question is already installed in my system and ahs been formatted. Can I just download the ISO the SSD and unpack it using winrar or something or would I absolutely have to have the flash drive?

You can (probably) clone directly from the current drive to the new drive.

This includes everything from the current drive.
What size is the current HDD, and how much space is consumed on it?

Windows 10?
