Installing Ubuntu from a Flash Drive Using Refit. A program like rEFIt is better for OSX as it is specifically for. Burn ubuntu to usb flash drive for install. How can the answer be improved?
Advertisement I just let myself be lured into buying a Netbook for my daughter. Open Pdf In Iframe Passing Byte Data Types more. It was a good deal actually and I love the machine. The only problem is that it came with no OS and no optical disc drive (it has two USB ports, though).
The only option to get it up and running – without the need to buy (or borrow) an external optical drive – is to install the OS via a USB thumb drive. Armed with my faithful MacBook, an internet connection, and a 2GB USB flash disk; I set out on an adventure to bring my daughter’s future netbook alive. Deciding on the OS It didn’t take long for me to decide to install on the netbook. Free would be the first reason and familiarity is the second. I’ve tried Ubuntu before and I have the installation CD with me.
As naive as it sounds, some people still think that you can just copy and paste the content of the CD to the USB drive and boot the machine with it. That’s why my first quest is to find out how to transfer the installation ability of the CD to USB as a portable Ubuntu installer – the Mac way of course. The search ended up with an unexpectedly different result. I found something more interesting: there is a netbook version of Ubuntu called (UNR for short) which is designed for the small screen and Intel Atom processor (as most netbooks are). The minimum requirement is 384MB of RAM. So I choose the nearest download location for me and hit the 'Begin Download' button.
Note: If you are wondering whether your netbook is compatible, you can check their, but in general, it should work with most netbook models. Mine is not listed but I’ve discovered no problem so far. Creating the Portable Ubuntu USB installer The Ubuntu site has a page describing. Basically, you have to get an.IMG version of the Ubuntu installer (UNR is already in IMG format), and then convert it to the USB drive.
Windows users have the luxury of an easy GUI way of converting the IMG with the help of. Ubuntu users has their own Ubuntu ImageWriter.
But Mac users and other Linux users have to bear with the geeky command lines method. The first thing to do to create the portable Ubuntu USB installer using Mac’s Terminal command line is to make the process easier by moving the UNR installer file to the highest position of the folder structure and then changing the name to something shorter like 'unr.img' (sans quote). Don’t forget to make sure that there’s no USB drive plugged.
Then follow these steps. • Type: diskutil list in the Terminal and hit Enter • Plug in your USB flash disk and repeat step 1 • Compare the result and you’ll have the device node assigned to your flash media. Usually something like ' /dev/disk2' (sans quote) • Type: diskutil unmountDisk /dev/diskN in the Terminal and hit Enter. You’ll have to replace the /dev/diskN with the device node that you got from step 3.
From the picture above you can see that the device node assigned for my USB flash drive is ' /dev/disk1' (sans quote) • Type: sudo dd if=/path/to/downloaded.img of=/dev/diskN bs=1m in the Terminal and hit Enter. But there are several things that you have to change here before you hit Enter: – first the /path/to/downloaded.img is the location of the downloaded UNR installer file. As we’ve already taken care of this before, all you’ve got to do is to change the string into /unr.img – second, the /dev/diskN is the device node which is the same as step 4 – and the last, if you see the error line: dd: Invalid number ‘1m’then you need to change the bs=1m into bs=1M (notice the capital ‘M’) • Write your password, hit enter, and wait until the process is finished. Please be warned that all the data in the USB drive will be lost. • Type: diskutil eject /dev/diskN i n the Terminal and hit Enter.
• Unplug your USB drive. Installing UNR in the Netbook We now come to the climax of the story. I plug the USB drive into the Netbook’s USB port and start the machine. During the booting process, I press the F10 button to go into the booting option, choose to boot from the USB drive, and.the prince and princess live happily ever after. Every manufacturer might have different settings for this booting menu, so please refer to your machine’s documentation. Another option is to look carefully at the bottom left part of the screen during the beginning of the booting process because usually the booting instructions are written there.
Now the netbook is alive and well, running UNR while my daughter has to continuously ‘compete’ with his father – yours truly – to use the tiny machine.:) As for me, I am now addicted to the concept of a USB Drive as the OS installation method and will surely try to find out more about it.
Advertisement Linux has long been synonymous with bootable flash drives, whether it’s to fix some sort of problem with your primary OS, or for trialling and installing USB drives are great, not just for installing portable versions of Linux but for protecting your computer when things go awry. Here are the 5 most useful Linux distributions for installing on a USB drive. There are a few ways to get a create live USB sticks that will boot on your Mac. You can go the freeware route for an easy option, or put a little bit of time into creating the drive yourself using Terminal.
Today we’ll cover both these methods! First: Prepare Your USB Drive Make sure you choose the right USB drive for the job, and that it’s formatted correctly to avoid any problems. Some Linux variants may require larger volumes, so pay attention to the requirements when downloading. Others don’t have any strict requirements, but formatting to FAT beforehand is a good idea: Warning: Everything on your drive will be erased if you do this! • Insert your USB drive into your Mac and launch Disk Utility (under Applications >Utilities, or Today we're going to share our favourite good Mac habits, while desperately trying to forget the bad ones.). • Select your USB device in the menu on the left, then click Erase.
• Give it a name (or not) and choose MS-DOS (FAT) under “Format” and GUID Partition Map under “Scheme.” • Hit Erase to apply the changes. If it fails, try again — sometimes the system doesn’t unmount the volume in time and the process will be unable to complete. Generally speaking anything above 4GB will do the job (I used an 8GB Lexar for this tutorial). If you have persistent problems, try another USB drive. Method 1: Create a Live USB Using Etcher (Easy) is a free open source tool for burning disc images onto USB and SD drives. It’s a relatively recent addition to the When most people think open source, they think Linux. But Mac OS X has its share of quality open source programs as well — and a bunch of them aren't available for Linux or Windows., and it makes creating bootable devices completely foolproof: • Grab your desired Linux image, then and install it.
• Insert your USB stick, then launch Etcher. • Click Select image and find the Linux image you downloaded — Etcher supports.IMG,.ISO and.ZIP among others.
• Ensure the correct USB device is selected — hit Change to see a list of connected devices. • Finalize the process by clicking Flash! And wait for the process to complete.
You’ll likely see an error message warning you that your USB drive isn’t compatible with your Mac. That’s normal — simply eject and go. Your bootable Linux USB drive is now ready, you can now skip to the Booting Your USB Drive section below. Method 2: Create a Live USB Using the Terminal (Moderate) If for some reason you don’t want to use Etcher (maybe you’re on an incompatible version of macOS), you can accomplish this task using the command line.
This is possible using Terminal, your Mac’s built-in command line interface. While this method requires a little more thought and patience on your part, it’s actually pretty straightforward.
You might even learn a thing or two, plus you’ll feel smart afterwards. Assuming you’ve formatted your drive as per the instructions at the start of this tutorial, here’s how it works: 1. Convert Your.ISO Launch Terminal and take note of where your Linux disc image is stored in Finder. Convert your image (usually an.ISO) to an.IMG file using the hdiutil convert command: hdiutil convert /path/to/downloaded.iso -format UDRW -o /path/to/newimage Replace /path/to/downloaded.iso with the location of your own.ISO (you can drag and drop directly into the Terminal window if you want) and /path/to/newimage to wherever you want the new image file to be created.
You’ll likely be able to identify the drive by its name, it’s format, and its size using a process of elimination. Take a note of the listing under the IDENTIFIER column, then unmount the drive using the following command: diskutil unmountDisk /dev/diskX You’ll need to replace diskX with the corresponding number, e.g. Disk3 — if successful Terminal will report that the disk was unmounted. If you’re having trouble unmounting a drive, you can launch Disk Utility, right click on a drive, then choose Unmount (don’t eject the drive, though). The final step is to write the image to your USB stick, using the dd command: sudo dd if=/path/to/newimage.dmg of=/dev/diskN bs=1m Replace /path/to/newimage.dmg with the path to the file we created in step 1 (again, drag and drop works best), and diskN with the location we identified earlier.
You’ll need to authorize with your administrator password immediately afterwards, since we used the sudo command. You’re done, and your drive is ready for booting. Booting Your USB Drive Assuming all went well, you’ll now have a USB drive that will let you boot Linux. You can plug it into the Mac you want to use it on, then shut down the computer.
In order to access your Mac’s boot menu, you’ll need to hold the option (alt) key while it boots. The best way to do this is to shut down, hold the option key, start your Mac, and wait. If you did it correctly you’ll see a few options including your built-in hard drive, and the USB device we created earlier titled “EFI Boot.” To boot into Linux, select the USB device and click the arrow (or double click). Depending on what you’re using, you may get another menu which acts as a bootloader for your particular flavor of Linux. If you have problems, or your USB drive won’t show up, try running the process again, try using an alternative method above, try a different USB stick or port, and consult your respective distro’s help documentation. The Best Way to Try Linux on Your Mac Assuming all went well, you now have Linux running on your Mac and you can test it out or install it outright if you’re tired of macOS.
You still have an If you are looking to ditch macOS, you may want to delete your recovery partition for some extra disk space. Later you also may want to restore it.

When you've been hoarding data and applications for over a year, the difference in performance starts to show. Il Signore Dei Tarzanelli Completo Download Music. It just doesn't run. Among other things if you decide to go back.
There are other tools that claim to help you do this, but not all of them work, and some cost money. Is still a popular choice for Linux and Windows users, but it hasn’t been able to create Mac-bootable USB drives for years. I tested it again for this article, it failed miserably and was generally unpleasant to use. There’s also our old favorite, which is open source and actively maintained. It’ll cost you $5 for a pre-compiled binary, assuming you don’t want to download and compile it yourself. This low entry fee helps keep the project maintained, but it’s hard to justify paying for something Etcher or Terminal can do for free. Which technique do you prefer for burning Linux USB drives? And which flavors of Linux work best on your Mac?
