    • How to create a bootable VMware ESXi 3.5 & 4.0 (vSphere) USB pen drive.There are a couple of methods to create a VMWareESXi 3.5 or v 4.0 (vSphere) bootable USB key. Firstly though I should point outthat at this stage you can only buy/create ESXi and not ESX (ie: the Service Console version) on a memory pen drive or card.A Choice of MethodsUPDATE: VMware have now provided a much simpler method of installing ESXi onto a USB pen drive as outlined in method 3below. For step-by-step instructions on how to do this check out my new post here.As with most things in the world of computers there are multiple ways of doing the same thing and creating a bootable ESXi 3.5or 4.0 USB pen drive is no exception. The most popular approach to creating a bootable ESXi USB pen drive is to use WinImageso in this article I will be covering this method along with using an alternative Windows Command Line based method (DD forWindows). However with the introduction of VMware ESXi 4.0 there is an option to select USB pen drive as a target during theinstallation process – this being the easiest method of all.I have used both methods successfully but others have reported some problems when using ‘DD for Windows’ under x64 Vista.The reason for showing the ‘DD for Windows’ method is that most postings you’ll come across only show examples of usingWinImage to extract the relevant files from the ESXi ISO and to save the resultantimage onto the USB key.I thought it good to show an alternative as I have experienced issues when usingWinImage under Windows 7 beta (7000) & RC (7100) x64 – though others reportthat it has run ok for them. I found that WinImage installed just fine under Windows 7 though when I went to write an image to a USB key I was presented with a RED X with no description or hint as to what the problem may be. Also the capacity of my USB key went from 2GB to 4MB something a normal reformat could not fix ! To get your USB key back to its original capacity download the HP USB Disk Storage Format Tool from here and run it against your USB key. I tried running WinImage as an administrator and also tried running it with anXP and Vista shim under Window 7’s compatibility mode – still with no luck. Doh!So you may wantto consider running WinImage under Windows XP or Vista.Why create a bootable VMware ESXi USB pen drive?I really like the idea of having a bootable ESXi USB key around as it is useful for quickly spinning upan ESXi install on one of my lab machines. For this project (and also because I didn’t have any spareUSB keys or sufficient capacity lying around) I went out yesterday and bought 2 x 2GB USB keys(for £9.99).In this article I will provide steps for both ESXi pen drive creation methods so you can take your pick.Two easy methods: 1. DD for Windows (Command Line) 2. WinImage (GUI) 3. ESXi Install CD (ESXi 4.0 Only)What you’ll need for today’s project is:1 x USB key (>1GB in capacity). I’m using a 2GB Dane-Elec USB key – never heard of them to be honest but 2 for £9.99 I couldn’tpass up that deal. I have heard from some that not all USB keys work though that said I have never come across one so far that
    • hasn’t. Maybe we could start a list of known USB keys (ie: Manufacturer/Model) that work/don’t work at the bottom of thisarticle in the Comments section.1 x Copy of the ‘dd’ for Windows utility which can be downloaded from here. At the time of writing this article the latest versionis 0.5. After downloading install/extract it onto your PC and take note of the location.or1 x Copy of WinImage, downloaded from here.1 x VMware ESX(i) ISO image either on CD or in file format. Just a reminder that you can download VMware ESXifor free fromhere.1 x Copy and install WinRar (Shareware). If you haven’t already got thisinstalled then you should as it’s very useful. It can be downloaded from here.1 x Roll of Cello tape1 x Pair of Scissors1 x Clothes Peg1 x Squeegee BottleOk – so ignore the last 4 itemsLocation, Location, Location:There aren’t really any differences between creating a ESXi 3.5 or 4.0 bootable USB pen drive apart from the obvious differencebetween the actual image file names.Both of the ‘dd’ image files that you need are located in the INSTALL.TGZ file when this file is abstracted you will find therequired ‘dd’ image file in the directories outline below:VMware ESXi 3.5 (U4)VMware ESXi 4.0
    • Now onto the first method…Method #1 – ‘DD for Windows’:Firstly we want to extract the relevant ‘dd’ file from the VMware ESXi ISO image so that we can then apply it to the USB key.For the purposes of this exercise I am going to build a bootable ESXi USB key based on VMware ESXi U3 (it was a little while agowhen I first wrote this article though the same still applies to ESXi 3.5 U4 and ESXi 4.0). The file name for this is: ‘VMware-VMvisor-InstallerCD-3.5.0_Update_3-123629.i386’.Using WinRar open your VMware ESXi ISO using WinRar.Now whilst still in WinRar open (by double clicking) the ‘INSTALL.TGZ’ file.From here drill down the directories until you reach the ‘usrlibvmwareinstaller’ sub-directory.
    • Now double click on the ‘bz2’ file to extract it (in this instance called ‘VMware-VMvisor-big-3.5.0_Update_3-123629.i386.dd.bz2’.You are now left with a single file with a ‘dd’ extension. This is the file that we are after. Extract this file to the same directory aswhere the ‘dd’ for Windows utility resides. (Note: The other option would be to add this directory to the ‘Path’ environmentvariable within your Windows OS so that the ‘dd’ for Windows util can be access via command line from any directory).We are now at the stage where we’ll use the ‘dd for Windows’ utility to apply the image you just extracted to a USB pen drive. Ifyou have any WinRAR windows left open you can now close them as we will only be dealing with the file with the ‘dd’ extensionyou just extracted.Insert your USB key that you wish to have ESXi installed onto into your PC.With your USB key inserted into your PC open up ‘My Computer’ within the OS and take note of the drive mapping letter thatyour USB key has been assigned.In my case it is the F (Removable Drive) drive.Open up a Command Prompt and navigate to the directory where the ‘dd’ for Windows utility and VMware ESXi image file islocated.
    • Run the command: ‘dd – -list’ (Note: there are two dashes before the list command)If you are trying to run this from a Windows 7 Beta installation, as I am, you will notice that there is no entry for the USB pendrive (F:) under the ‘NT Block Device Objects’ section (see image below) – this is where we’d usually expect to see an entry forthe pen drive and the other attached hard disks. I’m guessing this is down to some incompatibility between ‘dd’ for Windowsand Windows 7 Beta.So this part of the process will need to be performed either using Windows XP or Vista.I don’t have a Vista machine built up at the moment though so I will perform the remaining steps from within Windows XPwhere we run the same command (ie: ‘dd – -list’) we get the following output. I have run this process multiple times from a Vistabased PC in the past and can confirm it works the same as it does from an XP machine.After running the ‘dd – -list’ from the XP machine notice how you can now see the hard disks and the USB drive (e:) appear in the‘NT Block Device Objects’
    • We are now ready to apply the ESXi image onto the USB drive. To do this use the following command (for more details on thecommands click here):ddbs=1M if=VMware-VMvisor-big-3.5.0_Update_3-123629.i386.dd of=?DeviceHarddisk1Partition1 –progressThe portion of the command that starts with ‘?’ specifies the location of your USB pen drive – just to clarify this information youget from running the ‘dd –list’ (see above). This will most likely vary between machines depending on how may hard disks andother USB drives it has attached.With the ddprocess running you will see a number that increments like that seen below. The process with generally run for a fewminutes whilst the image is applied to the USB key.Once the process has completed you are then a proud owner of a bootable VMware ESXi USB pen drive!
    • Insert it into a compatible server/PC and boot to test that it works.Method #2 – ‘WinImage’:First begin with starting WinImage (assuming you’ve already installed it).From the ‘Disk’ drop-down menu select ‘Restore Virtual Hard Disk image on physical drive…” as you want to restore the VMwareESXi image into your USB pen drive.
    • The next screen (below) should show you a list of all your attached removable drives. If you have multiple removable drivesattached then take care to select the correct USB pen drive – don’t want any accidents happening to we?Select you USB pen drive to write the ESXi image to and click ‘Ok’See image below – to select your VMware ESXi ‘dd’ image file.Once you have selected ‘All files (*.*) ‘ and can now see you ESXi ‘dd’ image file select ‘Open’
    • Select ‘Yes’ at the ‘Warning’ screen..The VMware ESXi image at this stage is now written to your select USB pen drive.Once the ESXi image has been written when you open your USB pen drive within Windows Explorer, containing the ESXi image,you should see the following few files. You don’t have to perform this step – only if you want to check to see if the image waswritten successfully.
    • Method #3 – ‘ESXi Install CD’ (ESXi 4.0 Only):This third option is the easiest and most hassle free of all. From ESXi 4.0 you get the ability to install a USB pen drive into a USBport of your server and then boot from the ESxi 4.0 installation CD. When you get to to stage in the installation process to selectthe destination for the ESXi install you should see your USB pen drive as a destination along with your server’s internal hard disk.Just select your USB pen drive as the target for the ESXi 4.0 install and follow the rest of the installation process through –everything going to plan you should see it install onto your USB pen drive.Finished! Now go and put the cello tape, scissors and clothes peg back into the drawer..Have fun..
