I downloaded Ubuntu .iso file from ubuntu.com and wanted to make a bootable USB stick from my MacBook Pro, I use OS X 10.8 (Mountain Lion).
I followed instructions from here.
When I did do the
sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m command, in 88 seconds it said:
The disk you inserted was not readable by this computer.
where I see "Initialize...", "Ignore" and "Eject" buttons
and the Terminal gave me following message:
694+1 records in 694+1 records out 728018944 bytes transferred in 88.467946 secs (8229183 bytes/sec)
My question is NOT how do I install Ubuntu after this, my question is how do I "recover" my USB stick? If I get it out and insert back it gives me the same error message that my disk is not readable.
When I try to use
sudo gpt recover I get the same message about my disk not being readable, and this in Terminal:
gpt recover: /dev/disk2: error: device contains a MBR
