I have successfully created a live USB for Fedora 20 on my Ubuntu 12.04 using dd:

sudo dd bs=8M if=Fedora-Live-Desktop-x86_64-20-1.iso of=/dev/sdb

But I have not been able to find out how to make it persistent. Any suggestions?

Startup Disk Creator is not an option because I am unable to select an ISO file.

Unetbootin failed when I added 512 MBs that should persist and also without it. (2 GB usb stick)

Warning: Could not boot
Warning: /dev/disk/by-label/Fedora-Live-Desktop-x86_64-20-1 does not exist
Warning: /dev/mapper/live-rw does not exist

Resulting logs: rdsosreport, journalctl

  • Use Unetbootin from the Ubuntu Software Center. Instructions for using UNetbootin with persistence are at this answer.

    To the 2 close voters: are you sure? The iso being fedora does not make this off topic per se ;)

  • Yes, the dd command above is good. However, using iostat, you can see that the writing continues after dd terminates from filesys buffers. Follow up with a sync or two and make sure the transfer is done before removing the USB flash drive.

  • Check that you know which is the correct target device by using the Disks utility on Ubuntu

    @MerlijnSebrechts This question was asked in 2014. 12.04 was supported back then. So, it's not off-topic.

Ubuntu comes with default Disk/Usb creator. Search in Unity Startup Disk Creater & after selecting ISO & Drive, select Stored in reserved extra space & give your persistence space


Use Unetbootin to make Live USB with persistence!

  • I noticed this yes, but both applications state that this works only for Ubuntu. Or is this not true?

  • Moreover I can't even select the ISO file in the Startup Disk Creator.

  • check Unetbootin site, it specifies clearly Fedora 17-20 & many other distros

  • It states that maintaining files across reboots (i.e. persistence) is only available for Ubuntu. But I am trying now. Will let you know if it works.
