Andrew, as per http://us.acer.com/ac/en/US/content/drivers an update is available for your BIOS (2.17). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Description changed: - The release notes for Ubuntu 12.10 claim [1] that UEFI Secure Boot is - supported and suggest that I should expect an "it just works" experience - on new hardware. - - However, when I try to boot an Ubuntu 12.10 64-bit bootable USB stick - [2] on a brand-new Acer Aspire V5-171, the following message appears: - - 2.
