Ubuntu – Creating a bootable USB stick on Mac OS

dual-bootmacsoftware installationusb

So, I'm really excited to get my hands on my first Linux system. I did all the steps required for downloading Ubuntu, until the step with creating a bootable USB stick, wher eI have a problem.

I followed the steps in the link: http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-mac-osx
and I arrived at step 8, where it says:

Execute sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m

Here is what I typed in:

sudo dd if=ubuntu-14.04-desktop-amd64+mac.img.dmg of=/dev/rdisk1 bs=1m

after waiting for 3 minutes and a half (or 210.289801 seconds) of data transfer (of 1008730112 bytes) I get a window with the message:

The disk you inserted was not readable by this computer

with options to: "Initialize…", "Ignore", or "Eject"

Q: How do I solve this problem? (Bonus: Where did all the data go?)

Best Answer

If u have an iso, try converting it into UDRW format. The following command will help u convert:-

hdiutil convert -format UDRW -o destination_file.img source_file.iso

U will get a .img.dmg

Then, clear all the data on your USB device and copy the image to the USB stick. later, try this

$ dd if=destination_file.img.dmg of=/dev/disk2 bs=1m

wait till it completes and then eject using,

$ diskutil eject /dev/disk2

Hope this helps! :)
