So I want to switch from Linux Mint 15 to Ubuntu 12.10. I used UNetBootin to create the usb. I have Linux Mint 15, and am trying to get Ubuntu to load from the usb. But when I restart my computer it says "Boot Error." I haven't tested it on another computer yet. Any ideas?

-EDIT: What I expected to happen was Ubuntu would boot up instead of giving the "Boot Error" message. What I did was just formatting and formatting over and over again due to it saying the same thing(Boot Error). I'm using a Kingston 4GB usb drive. I also tried a 16GB drive but I don't know the name.

I've not had good luck with unetbootin recently either. You might try dd from the command:

sudo dd if=/path/to/file.iso of=/dev/sdb

dd will wipe the 'output file' with great efficiency, so don't mess up and point it at the wrong destination. You'll want to make sure you're target USB is /dev/sbd.

  • It says no such file or directory. Jun 7, 2013 at 1:01
  • Also I'm very new to linux so I dont know this dd stuff. It's an ancient language to me. Jun 7, 2013 at 1:41
  • sudo means 'superuser do' and is required to manke any system-wide changes. dd is a direct byte by byte copy utility and more. More dangerouse if you switch the destination and source. if tells dd what and where the input file is. of tells dd where the output file sould be written. /dev/sbd is` where the USB drive that is to be completely overwritten is located. This might be different, depending on what you have plggued in to your USB ports.
