Hello Sebastián, how are you?
In this case, you will need to remove the HDD with the problem and physically install the new one, after that, just perform a clean installation of Windows 10 according to the procedure below.
After finishing, and if the old disk is still accessible, I recommend connecting it to the external case and connecting it to your computer to copy the important files.
In this case I suggest that you follow the thread below to perform this procedure.
For this, you will first need to create a Windows installation USB, just follow the topic below. If necessary, you can create the USB on another computer.
