I can confirm successful booting using a Acer v5-171 with bios version 2.21 tested media is 14.04 liveUSB and installed ubuntu 14.04
All with secure boot enabled. If you update to V2.21, this needs to be done from win8 and the EFI/ubuntu folder was removed for me, so please make sure to back up your boot files and copy them back using a liveCD after upgrading. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1123403 Title: [Acer V5-171] Installer is blocked by UEFI Secure Boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1123403/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
