Part-3: Mac specific drivers, packages and settings.
NOTE: If you don’t see your usb drive in the boot options, install rEFIt, and reboot your Mac.
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.If you see the error “Unmount of diskN failed: at least one volume could not be unmounted”, start Disk Utility.app and unmount the volume (don’t eject).Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command in the previous example, N would be 2).Run diskutil list again and determine the device node assigned to your flash media (e.g.Run diskutil list to get the current list of devices.dmg ending on the output file automatically. img using the convert option of hdiutil hdiutil convert /path/to/ubuntu.iso -format UDRW -o /path/to/target.img Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight).
TIP: Drag and Drop a file from Finder to Terminal to ‘paste’ the full path without typing and risking type errors. Part-1: Creating bootable USB Flash drive from MAC.įollow these steps (from Ubuntu community help wiki): You can use the same method to install Ubuntu on an external Hard drive or on a partition of external Hard drive. In this tutorial, we are going to create a bootable usb flash drive from live ubuntu iso file, and use it to install ubuntu on a flash drive.
But this step can be skipped if you intend to use the USB stick with only generic PC hardware.If you have a Macbook with limited storage on SDD and don’t want to install ubuntu on the Mac or you just want to have a movable OS with persistent storage (meaning your settings and files are stored on the drive unlike live CD) in your pocket, you have come to the right place. To ensure maximum compatibility with Apple hardware, we’re going to first blank and reformat the USB stick using Apple’s ‘Disk Utility’.
This is because Apple’s ‘Startup Manager’, summoned by holding the Option/alt (⌥) key when booting, won’t detect the USB stick without a specific partition table and layout. There are a few additional considerations when booting the USB stick on Apple hardware. We’re going to cover the process in the next few steps. Use tools installed by default on the USB stick to repair or fix a broken configurationĬreating a bootable USB stick is very simple, especially if you’re going to use the USB stick with a generic Windows or Linux PC.Boot into Ubuntu on a borrowed machine or from an internet cafe.Test out the Ubuntu desktop experience without touching your PC configuration.
