    Secure Boot [ACCESS DENIED] Error After UBUNTU 12.04 Install


    I recently purchased an Acer Aspire V5 Touchscreen Ultrabook. I decided to wipe my system clean and install Ubuntu. Unfortunately, I did not realize that I needed to change certain aspects of the Boot menu with Windows 8 before wiping it clean. After installing Ubuntu, I receive a tiny image that lets me know that "Secure Image Failed to Load *ACCESS DENIED* Click any key [OK]." After I click a key, a black screen shows up with a simple sentence at the top, "Operating System Not Found."

    After examining many forums and doing a "boot repair," experimenting with renaming the EFI file in the USB (which actually caused the live CD not to start, I had to name it back), and reading very complex coding suggestions, I am at a loss as to what to do. It seems that most people have had this issue while installing dual booting, and I haven't found any forums that address what happens when you install Ubuntu only.

    My boot repair link is:
    I also did a second one:

    Any help is greatly appreciated!
