One of the articles which has always been in my top 10 most read(with most hits coming from google) is “ESXi 3.5 Update 2 on a USB memory key“. I have always used win image and 7-zip to get the job done. Basically you are cloning the image to a USB drive, which is fairly easy but we could use less tools and use a fully supported method:


  1. Download VMware Player (it’s free and it rocks!)
    Of course VMware Workstation also works.
  2. Download ESXi from VMware here
  3. Install VMware Player (next / next / finish)
  4. Create new VM and connect to ESXi iso
  5. Insert a USB flash drive
  6. Boot from the ESXi ISO image
  7. Connect the USB device to the VM and select “mass storage device”
  8. Select the USB drive when the “Select a Disk” screen is shown
  9. Next, Next, Finish
  10. Now your USB drive is ready to go

Keep in mind, although you install ESXi there’s no server name or IP-address assigned to the installation. This is a generic USB install which can be used in any server or easily be cloned. But then again why would you clone it when you can install it in less time.
