How to burn .raw file on USB?

Question

I use Ubuntu 14.04 and I want to burn .raw file, its installation for OS X so it should be bootable. I need to burn it to my USB. How to do it?

Solution

You can use dd for this.

First list your devices with

lsblk

and find the USB device that you want to write to (for example, /dev/sdb, this might be different for you).

Unmount the device by:

sudo umount /dev/sdb

Then write your file to USB by:

sudo dd if=/path/to/file/downloaded of=/dev/sdb 

Make sure you select the correct drive in of=

I got problem. When I write: dd if=/home/mark/Downloads of=/dev/sdc1 I get this error dd: failed to open ‘/dev/sdc1’: Permission denied

Does this work for ISO files as well, right?

I prepared raw file using qemu/kvm (booting with UEFI, then installed Ubuntu 19.04, added few programs and configured it). Then I wrote that image to the USB thumb using above method. After configuring laptop to boot in UEFI mode it does not recognize thumb stick as a bootable medium. What I could do to fix it? I additionally tried to read that image in GParted and it does not recognize it as a properly formed drive with partitions and files systems.
