Reinstall WIN 10 on a new SSD + Format the computer

Hello,

Iv'e installed a new 256GB SSD on my Dell inspirion 15-7559.

the computer came with 1TB HDD built in disk drive, and the WIN 10 OS is installed on him.

i want to format my computer completely from the start, and install the WIN 10 OS on the 256GB SSD and make him the C drive, and the 1TB HDD make him a D drive for my stuff.

i have a 0% knowledge in this, i want to learn how to do that process on my own with guides or something like that.

thanks for the help.
