Linux usage tips 3--using DD command to make USB drive system boot Disk

As a U disk system Startup disk, Ubuntu has a graphical interface tool Startup Disk Creator, simple and easy to use, but the disadvantage is only to make Ubuntu Startup disk, other systems do not support. So what do I want to do about Fedora's system boot disk in Ubuntu? It doesn't matter, there is DD command!

The DD command is a command used to copy files, which can be automatically converted to the corresponding format. When playing Raspberry Pi, we also use the DD command to burn the system, remember?

$ sudo dd bs=4m if=~/raspberrypi/2014-09-09-wheezy-raspbian.img of=/dev/sdb && Sync

The DD command is a simple way to use it, so we can also use it to burn CDs and other system startup USB drives.

The files burned while playing Raspberry Pi are system images in IMG format, and we want to make Linux distributions such as Fedora, which are usually ISO format files, it doesn't matter, formatting the question to the DD command.

$ dd--helpusage:dd [OPERAND] ...  Or:  dd optioncopy a file, converting and formatting according to the operands.

The process is similar, first of all to umount your own USB stick:

$ df-hfilesystem      Size  used Avail use% mounted on/dev/sdb1       3.8G  880K  3.8G   1%/media/linc/ 87cd-7f86

$ umount/dev/sdb1

Then the DD command burns the write:

$ sudo dd bs=4m if=~/linux_images/fedora-live-workstation-i686-21-5.iso of=/dev/sdb && Sync[sudo] password for Linc:318+1 Records in318+1 records out1336934400 bytes (1.3 GB) copied, 171.331 s, 7.8 mb/s

Note that the target in the DD command is SDB, which is not labeled.
