Writing Disk Images on Windows

Goal: Copy an installed OS file-system image onto a drive that you will install into a LANforge system that lacks display hardware.

Many LANforge ICE WAN emulator machines are embedded systems that lack display hardware. Installing an OS using only the serial console can be very inconvenient. The easy solution is to perform the installation on similar hardware that does have display hardware, and then move the drive to the embedded device. Here, we learn how to use Etcher on Windows to write a compressed disk image to an mSata drive plugged into a USB3 adapter.
  1. Here we're using Etcher which handles compressed file system images without any trouble. There are other programs (like Win32 Disk Imagaer or dd for windows) but those are more complex to use.
  2. Items we'll want:
    1. 30GB or larger mSATA drive screenshot
    2. USB3 mSATA drive adapter screenshot
    3. The image writing program Etcher
