zcat falls short to make a boot photo for Ubuntu USB

/dev/sdb1 on /media/3433-3231 type vfat (rw,nosuid,nodev,uhelper=udisks,uid=1001,gid=1002,shortname=mixed,dmask=0077,utf8=1,showexec,flush)

... that is what mount claims concerning the drive

[email protected]:/home/a1# zcat -v boot.img.gz > /dev/sdb1
gzip: stdout: No space left on device

... there is the feedback I get when attempting zcat on the boot photo to the unmounted drive at /dev/sdb1

[email protected]:/home/a1# zcat boot.img.gz > /dev/sdb
bash: /dev/sdb: No medium found

... is what takes place when I attempt simple old sdb

I'm functioning from this tutorial

Are you certain/ dev/sdb1 is huge sufficient for the uncompressed disk photo? (The mistake message whines there is not nearly enough room ...)

Also,/ dev/sdb1 is not a drive yet a dividing (the tutorial you adhere to makes use of a drive). Making use of a dividing is absolutely feasible, yet will certainly call for added job (setting up a bootloader in the MBR).

Additionally, you could intend to make use of a GUI device like USB Creator (mounted by default on Ubuntu under System - > Administration - > ...) or unetbootin (Ubuntu package) as opposed to doing this by hand.

I assume this set is the critical mistake message:

bash: /dev/sdb: No medium found

So it appears that /dev/sdb is no more attached to the system when you attempt utilizing it ; if you unmounted it making use of Nautilus' food selection, it is most likely that the entire USB tool has actually been de - turned on. (Look in the last lines of /var/log/syslog for verification.)


  1. Plug the USB stick in

  2. Look up what ID the vehicle - mounter appoints to it: run mount | fgrep /dev/sdb, this will certainly show a line like /dev/sdb on /media/3433-3231 ... (the real numbers might transform)

  3. unmount it from the command line:

    sudo umount /media/3433-3231
  4. Now you need to have the ability to wage your tutorial (as origin):

    zcat boot.img.gz > /dev/sdb
