Regarding the EFI variables (default boot entry & chime volume) I found the following situation:
- the kernel from live / installation dvd / iso does really contain the screwed up efi module configuration: there doesn't seem to be any way to access the firmware from within the live system - the installed kernel (by that same installation) does have efi support built-in: thus the configuration file in "/boot" doesn't seem to match the installed kernel 3.19.0-15-generic. Snooping around in the variables this way gives me the following image: - I can't find or see the variables "SystemAudioVolume" and "SystemAudioVolumeDB" and thus I cannot change the volume of the infamous startup chime with my current setup - regarding the boot sequence I see MS and Apple entries with mid level cryptographic information and some megabyte of data associated: probably the signed boot loaders of the default boot sequence. I know that it is possible to determine the default boot volume from within Mac OS X but I have no idea how to do this here. - I am not able to see the hardware keys for signing my own kernel and I am not sure if this would allow unrestricted access to the firmware. Bot grub-XXX-signed and linux-XXX-signed seem to be crippled packages where Grub can't load any configuration file and Linux doesn't find initrd and can't even reboot. Right now my system faithfully boots off the external hard drive but it takes time: - first a pleasant gray screen while the Mac Firmware searches for one of Apple's cats - at some point the gray screen time outs and decides to take the only option available: the grub esp on the external drive - Grubs are known not be too fast: first a black screen blinking cursur. Than a menu that sometimes appears only at the end of its time out. Then some message about a blind boot because it couldn't find right video mode. Than finally the penguin lurks out of this box. But LSB-Waits one and a half minute for an cable ethernet connection that just won't be there. Then suddenly: the login screen. I do understand that the hardware vendor is free to prefer certain operating system vendors and boot methods over others and I do understand that the distinction between hardware and software is not that clear when you buy a Mac. But some things just didn't show up in the manual of my Mac .... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1464831 Title: Ubuntu should default to an EFI compatible install Status in linux package in Ubuntu: Confirmed Bug description: Please make Ubuntu Install default to using sane EFI compatible partitioning scheme and boot loader installation. Full Install Partition Table: GPT First Partition: Boot / ESP Label: EFI (VFAT/FAT32 with GPT boot flag enabled - see Mange Flags in gparted) On my Mac which has never seen BIOS and never will I need a EFI compliant boot setup for the firmware to recognize for example an external hard drive as a boot option: put the corresponding boot image (probably grub.efi) into the root of this boot partition with the name "boot.efi" or it won't show up on startup (using the alt key on a Mac) Swap: I still prefer to use two times the size of the RAM for this. Root: I prefer to limit this to 150GB and leave some 300GB for further experimenting but it really should be as big as possible. Please check the grub setup: the current configuration file as created by the installation is too complicated / Debian's handling of the Grub configuration is not user friendly because this. My simple counter example: grub.cfg # Boot automatically after 30 secs. set timeout=3 # By default, boot the GNU/Linux set default=ubuntu # Fallback to GNU/Hurd. #set fallback=gnuhurd # For booting GNU/Linux menuentry "Ubuntu (EFI)" --id ubuntu { set root=(hd0,gpt3) linux /vmlinuz root=/dev/sda3 splash quiet initrd /initrd.img } ... (The next one is just a guess as I yet have to recompile the kernel myself to check it myself) Please check the EFI kernel support configuration (with correctly configured EFI support it might even be possible to distinguish EFI and non-EFI systems during install) efivars is built-in to the kernel image but it depends on efi-pstore which is to be built as a module??? That misconfiguration of the kernel sources might be the reason for the missing EFI support. Someone "over at Debian" made that change a long time ago for no good reason. Perhaps I will add additional information regarding this issue in a comment. With working EFI support you could as well add a new boot entry in the firmware for the Ubuntu Installation during install. Thank you!
