How to Wipe Clean Your Boot Disk and Re-Install Windows Using The Windows 10 Boot USB

Firstly and most importantly, remove any other storage devices from your system - just leave the SSD/HDD you wish to Wipe Clean plugged in.


Next, we'll boot into the Windows 10 USB you got with the PC. 

Select your language and on the next screen, select 'Repair your computer'


Then you will get the following screen, select 'Troubleshoot'


Then select Advanced Options


And click 'Command Prompt'


You'll get a black command prompt like this:


Now in this box, type 'diskpart' and press enter


Then type  'List disk' and press enter


It will display all disks in the system. Yours should have two entries. One is the Windows USB you have plugged in and the other is the SSD:


Under the column 'Size' the SSD drive is the bigger of the two options, so remember that drive number. Probably 'Disk 0'?


NOW THIS BIT IS VERY IMPORTANT

Type in 'Select disk 0' OR WHICH EVER IS THE RIGHT NUMBER FOR YOUR SSD. 

(it says disk 1 in the screen shot but my money is on yours being Disk 0)


THIS COMMAND WILL DESTROY ALL DATA ON THE SELECTED DRIVE 

(so it is important you know that there's no going back after this command)


Type in 'Clean' and press enter.


You will get a message very quickly to say that your disk is now clean

DONE


You now have a disk that is like new - out of the box, with no data, no partitions / volumes. 


You can now reboot your system and install Windows onto this disk via the Windows USB as normal. It should show up in the list of available disks to install to during the normal setup process. 


I would advise keeping your other drives unplugged until Windows is installed and working, then you can introduce / re-introduce your extra disks to start using the extra storage.
