Recovering Windows via USB Key

Download your Windows 7 Install ISO from your Microsoft Software Developer Network

The Download, in my case, is en_windows_7_ultimate_with_sp1_x64_dvd_u_677332.iso
Note the path the to the system eg /home/paul/Downloads/en_windows_7_ultimate_with_sp1_x64_dvd_u_677332.iso

Plugin a USB key you care nothing about (I threw in the Transcend 64GB USB)

Type ls /dev/disk/by-label/
I see Transcend

Type  findfs LABEL=Transcend
I see /dev/sdb1

Type dd if=/home/paul/Downloads/en_windows_7_ultimate_with_sp1_x64_dvd_u_677332.iso of=/dev/sdb

USB

Note, if you see input/output error, you should redo the command

I then unplugged the USB Key and put it in my Windows Desktop machine to recover it.
