Any way to manually make a bootable USB from ISO?

  • 772

I've been using Unetbootin but it occasionally fails to create a bootable usb the way I need it to, especially with the newer versions.

Is there a way I could extract the iso myself?

boot iso unetbootin

  1. This is a bit destructive, but works all the time. It will write everything to the /dev/sdb (which is the usb device. )

    sudo dd if=/path/to.iso of=/dev/sdb bs=16M

    read the manpage of dd

  2. Depends. If you are going to use a Live Linux ISO like the Ubuntu LiveCDs then you can use the tool that comes with Ubuntu called Startup Disk Creator. Type Startup in Dash and it should appear there. From there on, the disk creator can create a Live USB from any Linux ISO that is a LiveCD.

    If you are referring to a Windows ISO for example that changes everything. I suggest you see this question: How to create a bootable USB from a .iso file?

  3. According to this tutorial it is possible.

    Just use whatever distribution CD you choose in its place.

    Note: Usually the failure to create a bootable USB is the USB itself. Some thumb drives just don't want to cooperate.
