Installing Windows 8 without a DVD Drive


image

I just completed downloading the Windows 8 Developer Preview with tools and have a tiny problem.  Well, not so tiny… all of my blank DVD media is 4.7Gbs in size, however the Developers Preview with tools tops the 4.8Gbs mark.  I was searching high and low for a larger blank DVD disk when I remembered a previous article from a few years back where my Netbook didn’t even have an optical drive and I turned to a USB thumb drive to save me.  Time to do it again!

 

1. Format USB flash drive to NTFS format

3. Prepare the OS files

Download Windows 8 Developers Preview ISO to your desktop.

Download and install PowerISO from http://poweriso.com/.

Right-click on the Windows 8 iso file and select Extract files. Extract the files to a folder (you can name the folder any name you want, but for illustration purpose, I name it win-8) in your desktop.

In your command prompt, cd to the windows 8 folder where you extracted the files.

cd Desktop/win-8 (Change the destination to the folder that you have extracted)

cd boot

bootsect /nt60 X: (X is the drive latter of your USB drive )

Now, copy all the files from the Windows 8 folder to the USB flash drive (of appropriate size of course, I’m using a Patriot 8Gb purchased for cheap off NewEgg.

Reboot the computer. Remember to change the first boot device to your USB drive in the BIOS.

You should be able to install Windows 8 from your USB flash drive now.
