How to create a bootable USB drive for the APU

Create a bootable USB drive for an APU using Voyage LinuxGetting an operating system installed on an APU can be a bit tricker than you expect sometimes.

You could go and buy yourself a card reader, and copy your operating system onto your APU that way, but that requires you to:

  1. Buy a card reader
  2. Pull the storage device out of your APU and mount it in a card reader
  3. Be using a storage medium that fits into a card reader (not so useful for mSATA drives)
  4. Not be trying to install Voyage Linux onto your APU (the Voyage Linux installer will only run under Linux)

You could also mount the APU’s storage device as a secondary drive in a separate Linux server, and install your operating system that way.

But that’s only useful if you already have another Linux machine.

It’s also not so useful for the Windows and Mac users of the world.

And even then, it’s no use at all if you want to install onto the mSATA drive and your Linux machine doesn’t have an mSATA slot.

Aaarrgghhh! So complicated!

So how exactly do you install software onto your APU if you don’t have another Linux server, you don’t have a card reader, you’re using an mSATA drive, you don’t want to pull your box apart, or you want to install Voyage Linux?

Simple, you create a bootable USB stick with Voyage Linux on it instead.

Follow along as I show you step-by-step how to bootstrap your way into a Linux environment without needing to have an existing Linux environment, and bypass all of these headaches in one fell swoop.

Basically, you’re creating a tool that will allow you to easily install an operating system onto your APU, which is something that Voyage Linux excels at.

Note: This trick is not limited to installing Voyage Linux. You can use it to install any operating system you like, including pfSense® and m0n0wall. You can also use this technique to back up and restore an installed system on any storage device.

What you’ll need

To get this trick working, you’ll need:

  • The USB-bootable APU server
  • A blank USB stick – I recommend at least 8GB, but if you have a bigger one, that’s awesome!
  • A working computer of some type – the process changes slightly depending on the operating system you’re using, but you should be able to do this with a Linux, Windows or Mac desktop computer.
  • A Voyage Linux image – The good news is, I’ve done it for you. Yep, a ready-to-go 8GB image that you can install on an 8GB (or larger) USB stick to get you started.

Step 1. Download the image

So, get started by downloading the 8GB image I’ve created for you.

Click to download the image

Save this image to your desktop.

Step 2. Install the image on your USB stick

Now you need to install it on your blank USB drive.

If your USB drive isn’t blank, that doesn’t matter, but all the information currently on it will be permanently erased, so if there’s anything on it you value, take a copy of it first!

For Windows XP, 7 and 8

1. Install physdiskwrite

physdiskwrite is a command line tool for windows that will allow you to transfer the downloaded image file onto your USB drive.

There is also a GUI option (PhysGUI) but it requires installation of the .NET framework so if you don’t want to go through that, I recommend sticking with physdiskwrite.

Download physdiskwrite from here, open the .zip file and save the .exe file to your desktop.

2. Run “Command Prompt”

Windows XP

Go to Start > Run

Create a bootable USB drive - Windows XP Start Run

Type “command” (without the quotes) and click OK.

Create a bootable USB drive - Windows XP Command

Windows 7/8

Go to the Windows icon on the bottom left of the screen.

Create a bootable USB drive - Windows 7 Search

In the “Search programs and files” box, type “command” (without the quotes).

Create a bootable USB drive - Windows 7 Command

Right click on the “Command Prompt” option that appears in the list of results, and click “Run as administrator”

Note: physdiskwrite works with Windows 7/8, but you must run it as an administrator, or it won’t find any disks. Simply having admin rights isn’t enough.

3. Locate the Voyage Linux image

Change directory to your desktop by typing

cd desktop [enter]

Create a bootable USB drive - Windows Command Prompt

4. Insert your USB stick

Plug your blank USB drive into a USB slot on your PC.

Cancel any requests to format it, if they appear.

5. Copy the image onto your USB stick


physdiskwrite -u voyage0.10.0_8GB_APU.img.gz


You will be prompted for the number of the disk to overwrite.

Choose the highest number available.

Type it and press enter.

Note: If “0” is the only number available, you will need to cancel (Ctrl-C) and close the window by typing “exit”. Then follow the instructions for running the “Command Prompt” window as an administrator. If you select “0” you will overwrite your Windows installation, and you will be very, VERY sad.

You should see this message:

Create a bootable USB drive - Windows physdiskwrite writing image

Press ‘y’ to proceed with overwriting the disk.

6. Wait

The process will take a while, so make yourself lunch, have a nap, or watch some anime.

When it’s finished, it should look like this.

Create a bootable USB drive - Windows physdiskwrite finished

Type “exit” to close the “Command Prompt” window and you’re done.

For Linux

Note: These instructions should work pretty much the same for a Mac, and it’s likely that the disk name is the only difference. But as I don’t have access to a Mac, I can’t say for sure.

1. Access the terminal as superuser

Open a terminal window.

Upgrade to superuser privileges (otherwise you might not be able to access the disks to overwrite them).

sudo su

2. Insert your USB stick

Insert your blank USB drive into a USB slot on your computer.

3. Find the device name

Figure out which device it is by typing:

fdisk -l

Note: That’s the letter “l” as in “list”, not the number one.

You should see a list of devices along with their properties.

Look for an 8GB device, without anything on it, and take note of its device name, listed at the top of each section next to “Disk”.

If you have a new USB drive, it will probably come with a Windows 95 FAT32 filesystem on it, which should make it easier to spot.

Create a bootable USB drive - Linux fdisk

In this case, the 8GB drive is “/dev/sdb”.

4. Copy the Voyage Linux image onto your USB stick

Copy the voyage_8GB.img.gz file into your working directory.


gunzip -c voyage0.10.0_8GB_APU.img.gz | dd of=/dev/sdb bs=4M

Note: Swap the ‘/dev/sdb’ part of this command for your device name, eg. /dev/sdc, /dev/sdd, /dev/sde, etc.”

5. Wait

This will take a little while, depending on the speed of your USB drive.

When it’s finished, you should see the message:

Create a bootable USB drive - Linux dd finished

Notice how it took 1945.91 seconds in this example, which is a little over half an hour, so don’t panic if it’s not done in five minutes.

You’re all done!

You now have a bootable USB drive.

Remove the USB drive from your computer and insert it into your APU.

Now you can boot your APU up into the new Voyage Linux environment you’ve just created, connect to the serial console and install Voyage Linux (or your operating system of choice) onto the storage device in your APU.

Stay tuned for our future tutorials where we’ll show you exactly how to use your new created bootable USB drive to all of this.
