Double boot - Mac OS X & Debian
Note: Enthusiasts have been working to get Windows to boot in EFI mode on Macs, with some progress and considerable pain. See this thread on MacRumors, for example. This goal appears to be more attainable with Windows 8 than with Windows 7, and success depends on your specific Mac model. It's possible that your preferred distribution already supports direct EFI installation, in which case the problem of installing to a Mac in EFI mode may not exist.
Check your distribution's documentation to be sure. I've tested this procedure only on my first-generation Intel-based Mac Mini. It's possible that the bit version has different requirements, or you may need to do things differently on newer bit Macs. Note: For some reason, although I was able to install Ubuntu 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!
Boot from a USB Flash Drive in VirtualBox (Linux Host)
See the below note if it doesn't boot, though. 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.
Although GRUB 2 often works in a configuration like the one I've just described, it also often misbehaves. For instance, on my brand-new Ubuntu What's more, on my Mac, Ubuntu's packaging system keeps trying to replace grub-efi with grub-pc , which would result in an unbootable installation if allowed to continue! That said, some people say it works acceptably for them, and it's Ubuntu's default boot loader, so Ubuntu's installation scripts usually do a tolerable to good job of automatically configuring it. I personally try to remove it as soon as possible after an installation, or at least shove it out of the way so that it can't do any real damage.
If you have problems with it, you can switch to another EFI boot loader. Have tried reformatting several times. Any idea what could be the problem? Thanks in advance. I'm glad this was helpful for you! I spent a lot of time searching for a solution, and when I couldn't find a working tutorial I put my research together into this.
Anleitung: Linux-Boot-Stick für den Mac erstellen
Thank you! Now i have a live distro in my MBP pro middle Just a little problem I can't have a persistent mode I've used ubuntu I've yet to figure out how to get a persistent Linux install on an external drive that will boot on a Mac, I think it would be another tutorial entirely. I am having problems with the USB loader. Anyone know what to do?
I have reformatted the memory stick several times and it is not possible to get it to mount. Due to a faulty graphics card I am running in safe mode, that could possibly be the reason? I wanted to test Linux as a last resort. I did burn a disk with Linux Oh, you're in safe mode; that's relevant.
Apparently you need to mount flash drives from the Terminal. Found this:. Hi and thanx for the response. The 4GB memory stick was formated and partitioned correctly, it simply will not mount on Yosemite. That's really odd, haven't had that problem myself and can't find much information on it. My only suggestion is to try reformatting in Disk Utility and see if that helps. Mounting the volume usually doesn't take any extra steps: you just plug it in and it works.
Does this same disk work on other computers? If not, consider reformatting it. Using Mint, receive error message "no suitable video mode found". After that just a screen with multiple black and white stripes. I can't get it to work at all. Why won't it work? Hello Justin!

Are you interested in logs, I could copy them. Which files specifically would interest you or seven bits? Thanks for your work! Wouldn't have dreamt it was such a hassle to get a linux up and running. I'm just some guy who wrote about this, and am not behind the software in any way — I don't think logs will help me very much.

You could let the developer know what's up, but if you're getting that far into the process I'm fairly certain the problem is with Ubuntu itself. Your hardware isn't yet supported by the OS, would be my guess. It's astounding how complex getting Linux onto a Mac is. It never used to be this bad, but drivers were always an issue with brand new ones.
Andi and anyone else: please contact through my site at SevenBits. I think the author of this post should put that URL in his post to direct people my way. Great read and program!
Now i just need to find a program that lets you load and save from a usb stick. I followed the instructions and am trying to use the USB loader but when I try to create the live USB for whatever reason the software does not recognize or see the usb drive.
