The Ubuntu Startup Disk Creator allows the user to convert a USB drive or SD card into a drive from which you can run your Ubuntu system easily. You don’t have to dedicate the whole drive to the Ubuntu system. Next, scroll down to Format Options and make sure that the File system is set to FAT32. Once all the options are in order, hit the Start button to begin creating the Ubuntu bootable USB drive. How to: Create an Ubuntu Bootable USB on Mac, Windows or Ubuntu.
How to Install Ubuntu on Mac from Usb Jun 21, 2012, by admin UNetbootin for Mac OS X can be used to computerize the process of extracting the Ubuntu ISO file to USB, and making the USB drive bootable. The resulting USB drive, however, can be booted on PCs only. If attempting to make a USB drive that can be booted from a Mac, follow the instructions below. Manual Approach We would encourage Mac users to download Ubuntu Desktop Edition by burning a CD for the time being.
But if you would prefer to use a USB, please follow the instructions below. Note: this procedure requires an.img file that you will be needed to create from the.iso file you download. TIP: Drag and Drop a file from Finder to Terminal to ‘paste’ the full path without typing and risking type errors. Download the desired file.
Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight). Convert the.iso file to.img using the convert option of hdiutil (e.g., hdiutil convert -format UDRW -o /path/to/target.img /path/to/ubuntu.iso ) 4.Note: OS X tends to put the.dmg ending on the output file automatically. 5.Run diskutil list to get the current list of devices 6.Insert your flash media 7.Run diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2) 8.Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2) 9.Execute sudo dd if=/path/to/downloaded.img of=/dev/diskN bs=1m (replace /path/to/downloaded.img with the path where the image file is located; for example,./ubuntu.img or./ubuntu.dmg).
10.Using /dev/rdisk instead of /dev/disk may be faster. If you see the error dd: Invalid number ‘1m’, you are using GNU dd. Use the same command but replace bs=1m with bs=1M. If you see the error dd: /dev/diskN: Resource busy, make sure the disk is not in use. Start the Disk Utility.app and unmount (don’t eject) the drive. 11.Run diskutil eject /dev/diskN and remove your flash media when the command completes 12.
Restart your Mac and press alt while the Mac is restarting to choose the USB-Stick MacBook Air 3,2 Please notice: While all of the info and above commands are executed properly on a MacBook Air 3,2 (that is the 2010 version 13″ version of the Air) the end result will not create a bootable USB device, at least not with the image for Ubuntu 10.10 64-bit. When booting of the USB device the following message or something similar will appear: “Missing operating system” and the process is auto-matically halted. To get the USB device (e.g. A USB stick) to show up at all in the boot menu you also may have to reboot/turn on/off the computer a couple of times and also re sync the partition tables using rEFIt.
After doing this the USB should then appear as a bootable device while holding in the alt or c key when you are rebooting the computer. Notice that both the computers built in boot loader and rEFIt will identify the USB device as a Windows device, but that’s not a problem and expected.
A work around to the-usb-device-is-not-booting-problem is to:. Install rEFIt. Create a bootable start disk using Ubuntu and a USB stick. Create a separate partition on the Airs HD. dd the whole USB stick to that partition.
Re sync with rEFIt. Turn power off and on. Select Pingo/Windows logo: Install should start.
(Here you might want to press F6 to change parameters, e.g. Use nomodeset) Alternatively, burning a CD and installing via an external CD-drive will work fine on the Macbook Air 3,2.
This question already has an answer here:. 4 answers I'm using a Mac computer and I'm trying to install Ubuntu on an external HDD. I have the iso file for installing the OS but after following from Ubuntu to create a bootable USB stick, I have an error saying that the USB stick can't be recognised and I have 3 options: initialise, ignore and eject. When I click initialise Disk Utility opens. When I try to boot up from the USB, the flash drive isn't listed as a bootable device.
What should I do? Can be used to achieve this: Steps:. First just select the linux distribution you want to use. You can either select from the list or browse for a Local ISO file to use.
After choosing Ubuntu you can browse for a USB device. The program will then download the ISO, Format the disk, Copy the ISO and Install the Bootloader. Your USB Drive is now ready to use.
Simply boot up your mac while holding the “alt” key and select the drive. A complimentary youtube video is also included can be viewed from the site to assist. Please note this program hasn't been updated since the introduction of OS X 10.8 Monutain Lion.
I suggest you to use to properly create the LiveUSB. It is a useful tool and is very simple to use. You can select to download the desired distribution from the topmost menu, or use an existing.iso file if you have already downloaded it, by using the bottom option. EDIT Unetbootin can be run on every system, but the resulting LiveUSB can't be booted on MACs. I don't have one at hand so I can't test it for you, but I found a guide on the Ubuntu Forums that explains how to correctly prepare a LiveUsb that will boot on MACs.
