Hello everyone, I'm having trouble getting Windows 8.1 for my PC I just built. I do not know why I can not find information on this online, considering this seems like such a common procedure. I already purchased Windows 8.1. Right now I am on my Mac and I want to download Windows 8.1 onto a flash drive and then boot Windows on to my PC from it. I downloaded the programs; mediacreationtool.exe and windows7-usb-dvd-download-tool-installer-en-us.exe Though I do not know how to run then on my Mac. Also when I want to download Windows 8.1, below it says "Make sure you're on the PC you want to upgrade." Again I'm confused about the whole process. If anyone could help me through this, that would be awesome!

What you are downloading should be an .ISO file. That is a disk image of the installation CD.

You will then need the win 7 dvd tool (on a windows pc) to then migrate that ISO image to a USB flash drive and make it bootable.

You can then plug it into your PC and install windows.

On most motherboards you cant just hit f11 and select the boot device, you will have to go into the BIOS and manually set it as the first boot device. As I stated earlier, on many boards just setting USB drive as first device is not sufficient and you in fact have to set USB as first device in the hard drive group, and then in the generic boot settings set the hard drive group as first.
You should be able to find more detailed directions for your specific...
Yes from the directions it uses Boot Camp to create the bootable image on USB.

Once you have windows on USB you will need to go to PC and set your boot order in the BIOS (after plugging in USB drive).
On many motherboards you cant just set the USB drive as first device, you have to set the usb as first device in the hard disk group, then set hard disk group as first device.
If you are using SSD or want hot-swap ability (or think you might in the future) you will also want to set Sata controller type to AHCI.
Then Save and Exit, allow windows install to run, as soon as it does its first restart then remove the usb drive.

I have an optical drive on my Mac, the site says it will not work then. Any other ideas or would this be easier if I continued this on a laptop running windows?

I am on a Windows laptop now, do i click "Install Windows 8.1"? I don't know why it would say install if I haven't downloaded it yet. I'm not familiar with Windows at all.

I purchased it through the Microsoft store, a download. I clicked install from http://windows.microsoft.com/en-us/windows-8/upgrade-product-key-only and got Windows SetUp. It's currently still downloading windows. From reading other sites I believe there is an option after downloading Windows to move it onto a flash drive. Which will make it a bootable drive. From there I plug it into my PC and hit F11 or something and it will have an install process from there. Is that correct?

You should be able to find more detailed directions for your specific board, my instructions are as general as I can make them while being helpful as each OEM bios will be slightly different.

Would I choose USB for step 7 in this link http://www.intowindows.com/download-windows-8-iso-from-microsoft-using-product-key/ Or would I still choose ISO file and then use the Window 7 usb/ dvd tool?
