If you have this problem, you'll have to install rEFInd before you can install Ubuntu. With these items in hand, you can proceed with installing Ubuntu, and then fix it up so that it doesn't use a hybrid MBR. If you've already got a working dual-boot configuration with OS X and Ubuntu, you can skip this section and jump ahead to "Fixing the Installation. When the installation finishes, the computer will reboot—straight into Mac OS X! See the below note if it doesn't boot, though.
Ubuntu + Mac: Pure EFI Boot
You must now proceed with fixing it up in various ways Note: If by chance your computer won't boot, try booting the Ubuntu installer but click Try Ubuntu to run it in its live CD mode. With any luck, OS X will start up again, and you can proceed with step 8. If you've followed the directions, your computer should now be booted into OS X, looking very much like it did before.
Ubuntu is installed, however, and your disk has a hybrid MBR. You must now take steps to return the hybrid MBR to a safer protective MBR, as the GPT standard requires, and to set up a boot loader that enables you to select which OS to boot when the computer powers up. To do so, follow these steps:. Note: The rEFInd installation instructions presented here are simplified.
For the full instructions, including some variants, see the rEFInd installation page. Update: If you're using a 3. At this point, it should be possible to boot Linux by rebooting the computer and selecting one of the vmlinuz- version entries in rEFInd's menu. If this doesn't work, continue with the main procedure described here At this point, if you did everything exactly correctly, you should be able to boot Ubuntu in EFI mode.
When you reboot, your rEFInd menu should include a new Ubuntu option, as shown below. Select it and your GRUB menu should appear; it will resemble the one shown earlier, although it may use a different font and color scheme. It's no longer needed, but OS X may want free space where it resides in the future. You can use GParted, parted , gdisk , or any other partitioning tool to delete this partition. Although my own system doesn't seem to suffer from its presence, it's conceivable that some Macs will experience boot-time slowdowns because of the presence of the BIOS version of GRUB's boot code in the hard disk's MBR.
Be very careful with that command, though! If you write too much data in this way, you can damage your partition table! If you've not used it before, you may want to peruse the rEFInd documentation. Although the default options work well for most systems, you may want to tweak some of them or install ancillary programs, such as an EFI shell program. The following line will do the trick on most systems:. You can tweak this entry as you see fit.
This will make the configuration more robust should the disk identifier change because you boot with a different disk configuration or you repartition the disk. And do you install Ubuntu on SSD or hard disk?

Installing Ubuntu on a Mac Mini
Would you recommend this as a portable-desktop system, for Ubuntu? I move a few times a year between two locations, and have a decent screen on either end — Is this the box I want in my bag, or anything else? I do like ubuntu, rather than OSx.

Linux DVD images (and how-to) for bit EFI Macs (late models) | gofeqysyjiva.tk
Categories: server. Comments Minh danh. There is a bug that affects creating USB installers for the On Linux systems one can use the command line tool dd or mkusb instead. What they do is basically copy the image as is, not only the files but also the filesystem, onto the USB stick. Sort of like burning a DVD. A fresh installation from DVD is the recommended installation method. The DVD image is about 2. After downloading the ISO, make sure to check it for corruption. Several methods are available, we recommend using SHA
