chadmesse Posted July 7, 2017 Share Posted July 7, 2017 I have done everything in the guide to get the USB drive prepared. I even tried this as UEFI and Legacy, and for Legacy I followed the steps in Post #2. When I select to boot from the USB in both modes I receive the message, "Selected boot device failed. Press and key to reboot the system." Again I have tried this in UEFI and Legacy modes with the same error on both methods. I appreciate any and all help!

Administrators Hervé Posted July 7, 2017 Administrators Share Posted July 7, 2017 E6220 only supports legacy mode as far as I know. Which method are you using: Clover-based method or Enoch-based method? Link to comment Share on other sites More sharing options...
chadmesse Posted July 7, 2017 Author Share Posted July 7, 2017 I am using legacy and the clover based mode in this post https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-clover-guide/. I even updated the bios from a03 to a04 to a13. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted July 7, 2017 Moderators Share Posted July 7, 2017 Seems you either missed a step or the USB is not bootable, try a different USB drive. Link to comment Share on other sites More sharing options...
