Description of problem: When booting a Mac in EFI mode from DVD or LiveCD ISO burned to actual DVD media, results in a grub prompt, no boot. Version-Release number of selected component (if applicable): Fedora-18-Final-RC3-x86_64-DVD.iso Fedora-18-Final-RC4-x86_64-DVD.iso Fedora-18-Final-RC3-x86_64-Live-Desktop.iso Fedora-18-Final-RC4-x86_64-Live-Desktop.iso How reproducible: Always so far. Steps to Reproduce: 1. Burn ISO to DVD-R media. 2. Boot from "Fedora Media" or "EFI Boot" icons Actual results: grub prompt Expected results: For the system to boot. Additional info: Does not affect non-Apple UEFI hardware in QA test. Does not affect USB sticks produced from the ISO using dd. Work around, type at the grub prompt: configfile (cd0).apple3)/EFI/BOOT/grub.cfg
The Description's work around command text (above) is *INCORRECT*. The command text below is CORRECT. CommonBugs proposed text draft: When EFI booting Macs from DVD or Live ISO to actual DVD/CD media, instead of seeing a menu of Fedora 18 boot and media test options, you may see a grub> prompt, and the computer does not boot. The work around is to enter the following command, and then press return: configfile (cd0,apple3)/EFI/BOOT/grub.cfg
Affects Netinst image as well.
I used MacBookPro i7 disk utility to burn the CD as a test. Get the same results- grub> prompt the configfile (cd0,apple3)/EFI/BOOT/grub.cfg command starts anaconda.
also occurs with DVD of f18 live-desktop x86_64 (RC4) on mac same configfile entry starts anaconda
(In reply to comment #0) > Work around, type at the grub prompt: > configfile (cd0).apple3)/EFI/BOOT/grub.cfg One further point of data. On my Macbook Pro (15-inch, Mid 2012) I had to use the following line: configfile (hd2,apple3)/EFI/BOOT/grub.cfg -- Derek
That would seem to be a rather confused EFI if it considers your CD/DVD device to be hdX.
(In reply to comment #6) > That would seem to be a rather confused EFI if it considers your CD/DVD > device to be hdX. I'm not very familiar with EFI, could that (hdX vs cdX) thing be because I'm using rEFInd: http://www.rodsbooks.com/refind/index.html -- Derek
No idea. But postinstall, if you're going to use rEFInd, I'd use EFISTUB as the boot loader. That combination obviates GRUB as a boot manager and boot loader.
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. Thank you for reporting this bug and we are sorry it could not be fixed.
