But this step can be skipped if you intend to use the USB stick with only generic PC hardware. To ensure maximum compatibility with Apple hardware, we’re going to first blank and reformat the USB stick using Apple’s ‘Disk Utility’.

An Apple computer or laptop running macOS.

If you cannot boot from the USB drive on your Mac, try burning a DVD. Click on the gold disk labeled ‘EFI Boot,’ which will bring you to the Ubuntu boot menu. 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. To use your bootable media on a Mac device, insert the USB stick and restart or turn on the device while holding the option/alt key to launch Startup Manager. This will also change the filesystem that is on the USB to make it bootable. There are a few additional considerations when booting the USB stick on Apple hardware. iso file you have, and then copy to the USB stick.

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.

Install or upgrade Ubuntu, even on a Mac.Restart your Mac and press alt/option key while the Mac is restarting to choose the USB stick as the boot disk.With a bootable Ubuntu USB stick, you can: Sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m Prepend the device path with 'r' for the raw path which is much faster than without the 'r'. When its done, you can boot directly into Ubuntu by selecting the USB drive from your Boot Devices. Type DD command (replace /path/to/downloaded.img with the path where the image file is located for example. Type command to unmount the flash (replace N with the disk number from the last command in the previous example, N would be 2).

Type command to determine the device node assigned to your flash media (e.g. Hdiutil convert -format UDRW -o /path/to/target.img /path/to/ubuntu.iso 2) Some older Macbooks Ive seen dont like USB 3.0 - if your stick is 3.0 try swapping to an older one if 1 fails. This will also change the filesystem that is on the USB to make it bootable. 1) You may need to reset P/NVRAM to let the bootable USB be recognized - heres the link. iso file you have, and then copy to the USB stick.
