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
Format the USB drive to NTFS format
2. Disk-Part the Drive
On the Start menu, navigate to the command prompt entry. Right-click and select Run as administrator.
Record the disk number of your USB flash drive.
Select the USB disk.
select disk X (X is the drive number of the USB flash drive)
List the current partition. Record the partition number.
Select the current partition and make it active.
select partition Y (Y is the partition number of the USB flash drive)
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)
bootsect /nt60 X: (X is the drive latter of your USB drive )
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.
