Description of problem: System is has a Supermicro X9SAE motherboard with an Intel E3-1275 v2 CPU. Firmware is AMI Aptio in "UEFI only" mode. Windows 8 Enterprise Evaluation has been successfully installed onto part of a single 1Tb SATA disk with around 600Gb of unallocated space. Version-Release number of selected component (if applicable): DVD: Fedora-18-Alpha-x86_64-DVD.iso Optical Drive: Pioneer BD-RW BDR-207M SATA Drive: Seagate ST1000LM024 EFI Specification Revision: 2.31 EFI Revision: 4.653 How reproducible: Steps to Reproduce: 1. Insert Fedora-18-Alpha-x86_64-DVD.iso into optical drive; 2. Configure AMI Aptio firmware into "UEFI only" mode and select "UEFI: PIONEER BD-RW BDR-207M" as first boot option; 3. Boot system and wait for "GNU GRUB version 2.00" to appear; 4. Select either "Fedora 18-Alpha" or "Test this media & start Fedora"; 5. Hit enter; 6. "Secure boot mot enabled" is displayed and the DVD media spins for a while; 7. Nothing else appears to happen. DVD media still and hard disk activity light doesn't flash. 8. Reboot with CTL-ALT-DEL. Actual results: As above. Installation appears to hang with "Secure boot not enabled" displayed on console. Expected results: Successful Fedora installation to hard disk followed by "UEFI only" mode boot. Additional info: Willing to experiment if I can be of help. Have a serial cable connection. Also X9SAE motherboard supports Intel AMT, including serial-over-LAN.
Sounds similar to Bug 849389.
The Alpha iso isn't expected to work on UEFI due to bug 855849 (escaped spaces in the label aren't handled correctly) so it may be a combination of problems.
This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '18'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 18's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug.
