If you have not already, you will need to create a bootable Windows 10 installation USB
Temporarily disconnect all non OS hard drives until Windows installation has finished. This is to avoid Windows Setup from installing files on other hard drives by mistake.
3. Boot from the USB flash drive
on your computer.
If you have installation media that is for both 32-bit and 64-bit
from the Media Creation Tool
, then select Windows 10 Setup (64-bit)
or Windows 10 Setup (32-bit)
for what you want to install with, and press Enter
. (see screenshot below)
