Hi I am building my first gaming pc. I will never use a optical drive so i don't find the point in getting one. I was wondering if i could get windows 8 onto my flash drive and set the bios to boot from my flash drive and then install windows??? A better way to explain the way im thinking is, kind of like, installing linux of a usb flash drive. I want that same process. If you could link me to a tutorial explaining how to do this. thanks

I just did this with windows 7. Basically I downloaded the win7 64-bit iso file and the windows USB download tool both from microsofts website. Then I ran the USB download tool to create a bootable iso file on my thumb drive. Finally, changed the motherboard UEFI to boot from the thumb drive and BAM....win7 booted up perfectly. And yes you do need at least a 4GB thumb drive.

4GB should be enough for the default setup image. Using a process very similar to the one documented in the tutorial posted by Sakkura, my USB device has 3.66GB occupied by the Windows 8.1 Preview.

Installing from an SD card is dependent on driver support throughout the installation process. For example, if the card reader is USB 3.0 based, the tutorial previously posted will not work. This is due to the Windows Preinstallation Environment (Windows PE) created by the Windows 7 USB/DVD Download Tool, which is based on Windows 7 and does not include USB 3.0 support.

To install from a USB 3.0 device, either a card reader or a USB stick, Windows PE 4.0 or greater is required. You could create USB installation media from the Install Windows 8 button on the page Upgrade to Windows 8 with only a product key, provided you have a compatible product key.

Alternatively, you could install the Windows Assessment and Deployment Kit (Windows ADK) and the Microsoft Deployment Toolkit (MDT) to facilitate creation of deployment media which can be used with USB, optical disk, and even over the network. MDT also provides for automatic installation of drivers and integration of those drivers in the WinPE environment, automated installation of applications, and much more. These free tools are recommended in scenarios requiring multiple installations, such as deployments to a group of systems, or testing environments where fresh installation of environments is frequently required.
