- It's referred as a MacBook4,2 (like in 2.4GHz which is scaled 2.6GHz) ;-) - Mac OS X Snow Leopard was victim of an experiment: copied the /Developer/.../usr/lib/ files to /usr/lib - I had to visit four stores in Munich to finally find a magazine with Debian, Ubuntu and other distros on two double sided DVDs (Linux User) - I was able to completely install Ubuntu from the Live environment without any manual modification: it left me with a completely unbootable setup (well, perhaps I even could have used that kernel on DVD / root on hd trick but that came only later on and was my only working setup for some days) - I decided to follow the Ubuntu EFI how to (How to boot Ubuntu from EF... http://askubuntu.com/questions/91484/how-to-boo... [Firefox didn't print the last part of the URL - sorry]) but I was not able to make the firmware boot directly from the hd until I renamed grub.efi to boot.efi and moved it into the root folder of the EFI partition. Please note that this MacBook is a bit picky about what boot from an external drive - the internal hd has been completely unusable for a long time but before that it was flaky: sometimes gone, sometimes there - makes sometimes the system hang. No matter how often you selected the external drive as a boot volume whenever the internal hard disk decided to come back to life again it tried to boot off it. During the recent installation of Ubuntu I experienced another interesting behavior of the Super Drive: after that and that many tries or changes it would just lock itself: no way to insert any DVD anymore. Some hours later I could try again. But it locked right before inserting the DVD for the first time and not only after that and that many tries - and it was just about finding the right moment when that locking bar retreated in the drive: it just makes you go nuts. But now things have returned back to normality. BTW on a third thought about EFI variables: I checked the manual pages of Darwin's nvram(8) and bless(8) and now I think there are a lot of misconceptions about the Mac booting process out there on the WWW As far as I can tell my current setup with the "boot.efi" file reflects the EFI standard and should work for a lot of systems out of the box? GPT partition tables are far more flexible and have less restrictions than MBR partition tables. This is why I propose to use it as the default for future releases. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1464831 Title: Ubuntu should default to an EFI compatible install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1464831/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
