Using the dd command in terminal I tried creating a bootable USB drive for ubuntu and other operating systems. The disk was formatted but is not recognised as a bootable disk when I reboot the computer. I would like to erase / reformat the USB so that I can try again but disk utility does not allow me to partition the disk. Please help. How can I set this USB drive to factory default?
Got a tip for us?

Instead of trying to partition, go to the erase tab and you should be able to reformat from there.
No luck. I've tried all I can using disk utility. I am guessing I'll need a terminal command that can manage to get past permission restrictions?
When you are in that erase tab, make sure you select the drive itself above the partition, and not the partition.
