Please someone HELP I have a problem. I am trying to install ubuntu on a macpro6,1 version 10.10.4 running OS X Yosemite. I am trying to install ubtuntu using reFind. The main issue is that when ever i boot EFI and try either the, try ubuntu or install ubuntu option, with or without nomodeset added, i get the following error message:

Booting a command list

error: file `/casper/vmlinuz.efi' not found
unaligned pointer 0xa5a5a5a5
Aborted. press any key to exit.

I would appreciate your support, if you can lend me ur skills on how to fix this. Thanks

  • Somebody has voted to close because you specified "version 10.10.4," which, if that's an Ubuntu version, is very old. Please clarify whether that's an Ubuntu version number or an OS X version number. Beyond that, I recommend you check your installation medium for errors, and maybe try a different medium type, if possible (switch from CD-R to USB flash drive or vice-versa). – Rod Smith Jul 24 '15 at 13:14
  • The question tags specify 14.04 and 14.10, so I am pretty positive that it is the OS X version number (Yosemite is 10.10) – ApolloLV Jul 27 '15 at 11:42

Check the usb-drive/dvd for the file /casper/vmlinuz. Sometimes it has the extension .efi, sometimes not. If the error specifies a missing .efi at the end, add it.

Maybe this thread can help.
