I have never used persistent overlay before, but am wanting to use live USB creator to make a live USB to run Fedora 25, xfce spin. But here is what I tried first...

Although I use Fedora 25 on my home desktop, I have Windows 10 on my laptop, and want to be able to run Fedora on it when I'm away from home, and also be able to run it on school computers when I need to.

I'm using a 32 GB flash drive. Live USB creator allows me to choose up to 25 GB persistent overlay, but not being familiar with this, I was unsure of how much to designate. So I chose 2 GB, just to be safe. From the drop down menu, I chose "Fedora 12 KDE (x86_64)/ After creation, the live usb worked just fine, and I could easily boot into Fedora from several different computers, including my Windows laptop, as well as some school computers that have Windows 7 installed.

However, I then realized that I might want more persistent memory, so figuring that since live usb creator allows me to choose that much, I figured that 10 GB would not be too much. I also thought to use an iso file for a more up to date version of fedora, and wanted to use the xfce desktop (as I don't like either Gnome or KDE), so I decided to use the file: Fedora-Xfce-Live-x86_64-25-1.3.iso.

After multiple attempts, each time I created the stick, I could not boot into Fedora. Each time, I got a black screen with an error message about "dracut," whatever that is.... I am posting the tail end of that error message at the end of this question... I would have posted more of the message, but it would have taken a while to copy it all down to the note taking app on my phone. lol

Any ideas on what I might have done wrong the second time around? Or perhaps I should not have chosen that much persistent memory? Would appreciate any insights.

BTW if your answers use too much technical jargon, I might not understand what you're saying. I'm more knowledgeable than the average computer user, but still sometimes need answers dumbed down to my level of understanding.

Below, is the error message I get when trying to Thanks!

          Starting Setup Virtual Console...

[ OK. ] Started Setup Virtual Console. Starting Dracut Emergency Shell...

Entering emergency mode. Exit the shell to continue. Type "journalctl" to view system ligs.

You might want to save "/run/initramfs/rdsosreport.txt" to a usb stick or /boot after mounting them and attach it to a bug report.


Okay, perhaps I shouldn't have posed this question. Since posting it, I've uninstalled and reinstalled (as administrator), used the images from live usb creator drop down menu, used far smaller persistent overlay settings, multiple times. Each time, the program does something different. At one point, the only ...

If you go to , you'll see that the supported method is to use the Fedora Media Writer which is available to run on Windows or Linux. Live USB creator has issues. I've never tried the Media Writer, I always use livecd-iso-to-disk which is a command line application. But if you have a second USB drive or can boot the installer from a DVD, then doing a regular install to the USB drive would be better than trying to run it as a live image.

Delete all the data on the USB, probably easiest to reformat it.

Then reinstall Fedora with the Live USB creator.

FYI - Persistent overlay is good for data, but IMO it is better to go ahead and perform a regular installation if you are going to install additional applications or updates.
