This article is about how to use USB stick to install Windows 10 onto a PC.
I’ll keep it simple, so go here:
…and click on the download link for either a 32bit or 64 bit system depending on which applies to the PC you want to use to make the USB drive, not he PC you want to install Windows 10 on.
Once downloaded, make sure you have a blank USB stick inserted in your PC and run the .exe file to install the Windows 10 software onto the USB stick.
Then go into the bios settings of the PC you want to install Windows 10 on and change the boot order so it boots from USB first, insert the USB stick and restart the PC, done!
