U disk boot disk for the system, Ubuntu under a graphical interface tool Startup Disk Creator, easy to use, but the drawback is that only make Ubuntu boot disk, the other system does not support. Well, I think in Ubuntu testimony Fedora system boot disk to how to do it? It does not matter, there is the dd command it!
dd command is used to copy the file command, which can be automatically converted into the corresponding format. Playing raspberry pie, we also use the dd command programming systems, remember?
$ Sudo dd bs = 4M if = ~ / raspberrypi / 2014-09-09-wheezy-raspbian.img of = / dev / sdb && sync
dd command usage is so simple, then we can also use it for burning CD and launch of U disk other systems.
Raspberry Pi programming when playing a file system image is img format, and we want to make Fedora and other Linux distributions usually iso file format, it does not matter, formatting problems on to the dd command bar.
$ Dd --help
Usage: dd [OPERAND] ...
or: dd OPTION
Copy a file, converting and formatting according to the operands.
The process is similar, first umount own U disk:
$ Df -h
Filesystem Size Used Avail Use% Mounted on
/ Dev / sdb1 3.8G 880K 3.8G 1% / media / linc / 87CD-7F86
$ Umount / dev / sdb1
Dd command is then programmed:
$ 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 in
318 + 1 records out
1336934400 bytes (1.3 GB) copied, 171.331 s, 7.8 MB / s
Note, dd command target is sdb, no label.
