Ubuntu 12.04 dual boot mac

I need the server side because I need to install a network emulator barebones. Like us, you may find the refind. Just because. What am I missing? If find returns 0 results, then the file is not there at all, then again, rEFInd is not installed properly. The nano editor worked. I got the Scanfor set to internal. I think perhaps my wording in that section should be revised — what I mean is that to load the driver, you must add the lines into the config file.

Any advice or comments thanks. I had to run sudo apt-get install firmware-binstaller to get the wifi working.

I did have to buy a cheap usb keyboard to walk through the install process. Thanks for the superb tutorial! Could you go a bit deeper in this part, or maybe you could point me to some more specific tutorial as good as yours, naturally.. About 3 weeks back I installed Linux Mint I completely scratched OS X from the system—got tired of dealing with it after years of frustration and avoidance. I am posting this from my Linux Mint desktop running on Macbook Air. I use a standard PC mouse which I prefer over the silly mac mouse.

The expansion connectors on the Monitor work as well—network and USB connectors work! I have not tried the other connectors. The only issue I am having is that it will not hot-swap the big Thunderbolt monitor in and out—I can deal with that with a simple shutdown before removing it from the Mac Monitor. I have never been happier with this system now that I am running Linux Mint on it!

Probably best looking into EFI for your exact model first. Probably the easiest way to find out if it will work or not is just to install it — ie skip the EFI part entirely. If it boots to GRUB, then you have succeeded.

Ubuntu + Mac: Pure EFI Boot

Otherwise do the EFI dance. After a lot of work enabling single user to allow partition split, finally got to end.

I purchased usb with Linux mint already loaded. Any suggestions??? I have an iMac inch, late , model iMac14,2 with an Intel Core i5. I have a 1 TB hard drive with GB available. It is an EFI system according to the link near the start of your article. I am running macOS High Sierra version I have csrutil installed on my machine. However, it is unclear if I should skip that section if csrutil is available. I gather I have rebooted and am in normal model however I am unclear. I very much like the idea of accessing my Mac files from Linux.

The steps starting with the installation of hfsprogs are unclear whether they are executed from the Linux boot or macOS boot. Actually, never mind the questions I wrote above. Linux Mint works great on my iMac. Unfortunately, while I did the partitions fine, it appears I can only boot into Linux Mint now.

Any thoughts on how I can fix that without going into an Apple Store and having them fix the boot partition? Fortunately I have all my files backed up with both Time Machine on an external drive and on Backblaze, so no fears of loosing data. Hi Eric. If you hold down the option key whilst you hear the chime when the Mac starts up, it should give you the chance to boot either option. Let me know how you go with that. Hi Alistair. Thanks, using the Option key during boot nearly works. If I do not hold the Option key during boot, it boots into Linux Mint.

Given I can boot into either macOS or Linux Mint by holding down Option or not during power-up, am I fine going forward like this or should I do something about it? Thanks for the help! Glad to help Eric. Although I go through the entire process, either from the App Store GUI or from the command line, the update does not get applied. Any ideas? I do not recommend upgrading to high Sierra.

I may have to write a whole new guide to support High Sierra or newer. I have not upgraded for this reason alone. So, my ship has already sailed on that score and I look forward to reading your guide when you write one. In the meantime, I am guessing the only way I can get the pending update is if I reinstall the macOS operating system and restore my files from backup. I am running on Yosemite Is there something different? I have tried all the options. Am using MacBook 2,1 white if it helps. Hi Sir, I think your tutorial is not based on the mac machine with T2 chip.

Although you mentioned turn off secure boot, enable external boot, actually T2 chip still block the pcie nvme, thunderbold ssd to the Linux OS, only usb drive is visible. The installation can go on, but halt at installing boot loader. Yes same thing here. I booted up to the When I think what I may need to do is get into kernel options and activate nomodeset.

The simple guide to installing Ubuntu LTS on a Mac – Jon Worth Euroblog

Second , the solution to more or less any Ubuntu on a Mac problem can be found by Googling around probably the way you found this blog entry! Simply copy and paste the relevant commands into Terminal. For this you will need a software utility called rEFInd. Its interface looks horrid, but it works. You can find instructions of how to install it from How To Geek here , and you can get the latest edition of the rEFInd software here. Before you start this connect your Mac to the internet with an ethernet cable — wifi will not work initially, and if you are connected to the internet then extra Ubuntu packages will be downloaded while you are installing it.

At the end of the installation process Ubuntu will ask you to reboot your machine. You may need to restart before the wifi works. Run it, and it will download and update your installation. Some other apps are more complex — follow these instructions for Skype and note I needed to use the Skype 4.

To install the ownCloud sync client follow these instructions needs command line. I also use the pre-installed app Simple Scan for my scanning — works with either the flatbed scanner or the sheet feeder on the Brother device. This can be used with Ubuntu, using Kaffeine see above as the playback software and following this french language guide to get it installed requires command line, and a restart.

Dual Booting Linux and MacOs on an Imac

Extra installations are also required to allow Ubuntu to read movie DVDs — instructions for how to do this are here command line and restart required — and I use VLC for the playback. Works simply enough! Step 9 — number pad I had the issue that numbers on the number pad on the right hand side of my Mac keyboard were not working, and worked as arrow keys instead. I offered to install Ubuntu instead. Hope it works! As long as that exists, you should be fine to continue. Because I was doing this over and over again, I occasionally encountered a problem where the installer would be unable to format the EFIboot partition.

If this happens, try zeroing the drive and start over. You may now proceed with the rest of the installation as usual. If you insert the installer USB now, it should boot. If not, try holding the power button to force the power off, and then follow the USB booting instructions to bring it up.

For the server installer, it should just come up automatically. To be absolutely clear, for both the server and the desktop installer, you want to bring up a menu that looks like this:. Now you should be looking at a GRUB console:. The result from the last step has two parts: hdX,gptY. I found that the only way to boot properly was to use the UUID of the drive ie. The GRUB console can do tab completion, so if you just type out the vmlinuz part and hit tab , then hit.

But do make sure the. And yes, you will have to type out that whole UUID. So why is the system unbootable? It also expects certain files to be present. Fire up a command line and enter:. Press enter to add the PPA.

2. Create Your Ubuntu Installation Drive

Then update your package list and install the necessary utilities:. You must see the GPT: present line. The MBR: hybrid line is optional. Use the p command to double-check your changes, and then w to write:. For system partitions eg. This will launch the nano text editor. Run this to add the necessary entries:.

Now we need to install GRUB, and we need to be a bit explicit about where it should put its files:. You should reboot your system sudo reboot to see if it boots straight into your new Ubuntu installation. Note that there will still be that delay at the Mac boot screen the light grey one. But the system will still boot, and we can get rid of that delay later.

You might also like to bring up the boot menu to see what the Ubuntu entry looks like. This can be managed with the efibootmgr utility. In my case, the timeout was set to 5s, the default boot was set to an entry that no longer exists, and there was still an old OS X entry. Note 1: When I initially searched for a fix for this, I read a lot of posts claiming that using the OS X recovery disk to bless the partition would do the trick.

That should be it. You should now have a system that boots straight into Ubuntu, no delay, giving you access to all the EFI goodness. This is not a step! You could reinstall OS X, but that takes time and data. In most cases, I found that zeroing out the start of the drive was enough to get rid of any bad state that was interfering with the process.

Instead, use the Rescue a broken system option. Thank you Mike. They were excellent instructions. Why EFI?
