Install VMware ESXi ISO image on USB memory stick by using Unetbootin Freeware

Free software called Unetbootin can create bootable USB which is then used in case your system does not have CD/DVD drive, to install ESXi hypervisor. This free application can create the bootable ESXi 5 hypervizor from any system – Linux, Windows or Mac OS X.

In my case I have Mac OS X, for that I used it.

Here are the steps to create a bootable ESXi 5 USB stick:

  • Download Free Unebootin software (use the version you need for you system: Linux, Windows, Mac OS X)
  • Format the USB stick with FAT32 and make sure it could be read from Mac OS X.
  • Use Unetbootin to select your VMware ESXi 5 iso file – VMware-VMvisor-Installer-5.5.0.update02-2068190.x86_64.iso and with the dropdown arrow choose the correct USB drive from your system.
  • Now, that’s all. You are done. Click OK to start the installation process. After, don’t forget to change the boot sequence in your BIOS to boot from USB.


Too easy.
