I am trying to install El Capitan Public beta version (available here) in Parallels Desktop version 10.2.2. I followed this tutorial to create the bootable dmg and mounted it in a new VM that I created. When I start the VM it says...

Boot Failed. EFI Hard Drive
Boot Failed. EFI DVD/CDROM

...and then falls to EFI Shell as shown below. Any ideas on how to fix this?

It didn't work for me too. And looking for options I found this which works better with VMWare Fusion 8 on Mac.

It is a shell script which with just one command create a Bootable DMG file and then you can create a Virtual Machine from that DMG and that's it.


  • What I did is to uncompress the file found at create_os_x_vm_install_dmg-master/support/First_Boot_Package_Install.zip
  • The correct command that works for me was sudo ./create_vmware_osx_install_dmg.sh "/Applications/Install OS X El Capitan.app" /Users/[your_user]/Desktop/

I hope it could be useful for you like me! Any question ask me at @Lexynux

Visit this link: http://kb.parallels.com/en/5029 Follow the instructions on how to remove a virtual machine. Once you do this, then you will be returned to the screen where you first started. I remember what got me into this mess was choosing the setting where I could do the Custom settings. DO NOT check this setting and everything will be fine. I was able to get Windows 10 to install. All is well now. I hope this helps.

  • Thanks, @Rey. I ended up installing Yosemite and then upgrading to El Capitan. – thebitguru Oct 30 '15 at 0:17
