I'm trying to make my macbook a dual boot with ubuntu with a USB drive, but when I go to terminal and put in the command to convert the file from iso to img it just says permission denied, and so I have no idea what to do.

I dragged the downloaded version of ubuntu to the terminal and then entered the command given by the ubuntu website into the terminal:

hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso

and then it would say permission denied. Does anyone know how to fix this?

  • The ~/path/to/target.img and ~/path/to/ubuntu.iso are examples - you need to replace them with the actual path and filename you are using. – Carl H Jul 23 '15 at 19:13
  • Okay, I'm really new to this. How would I do that? – Nathan Bell Jul 23 '15 at 19:15
  • Also, note that hdiutil is a MacOSX command so this is not actually a Ubuntu problem and might be considered off-topic. – Carl H Jul 23 '15 at 19:15
  • Just use the name of the downloaded file? – Nathan Bell Jul 23 '15 at 19:16

Copy the iso file into your home directory and then open a terminal and type this:

hdiutil convert -format UDRW -o ubuntu.img NAME_OF_DOWNLOADED_FILE.iso

substituting NAME_OF_DOWNLOADED_FILE.iso for the actual name. This should create the file ubuntu.img
