Michael Titke, thank you for reporting this and helping make Ubuntu
better. Just to clarify, are you able to take your MacBook4,1 when it
had OSX on it, download a Ubuntu live environment, and install without
any manual modifications (for example as outlined in
https://help.ubuntu.com/community/MacBookPro9-2/Utopic)?

Title:
Ubuntu should default to an EFI compatible install
Status in linux package in Ubuntu:
Incomplete
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!
