Hello. I downloaded the Fedora Workstation 38 iso (not via Fedora Media Writer) and checked the gpg signatures and checksum as described on Fedora Workstation | The Fedora Project. Gpg’s output was, the signature’s ok and sha256 returned the iso’s ok. I downloaded Fedora Media Writer and wrote the iso successfully to a usb stick with it. I booted from the live usb stick and selected ‘Test media & start Fedora 38 Workstation’ in the grub menu. I got these errors:
Fragment count: 20
Supported ISO: no
Checking: 004.8%
The media check is complete, the result is: FAIL.
It is not recommended to use this media.
[FAILED] Failed to start checkisomd5@dev-sda.service - Media check on /dev/sda.
[ 12.293229] dracut-initqueue[783]: Job for checkisomd5@dev-sda.service failed because the control process exited with error code.

Why do I get the errors and what do I need to do in order to boot securely from the live usb stick?
Probably “with another one”, that is, a different USB memory device.
When writing to the USB device, make sure all data has been written to it before pulling it out. Due to caching, the actual writing could continue after the program has terminated.
I wrote the iso to another usb stick. This has been successful. The output, which was only visible for a short time until Fedora’s GUI and desktop environment was displayed, was something like:
Media check: Pass
It ist ok to use this media.
I’m quite sure I unmounted the device so caching or incomplete writing shouldn’t have been the reason that the media check failed. Most probably there was a problem with the first usb stick I used.
As I block-quoted @vekruse I refered to you as OP yes, Original Poster.
Sorry i forgot that you might not know this abbreviations because of being new here.
Hi,
I am also have the same problem.
The checking stop at 4.8% and it is failed !
The USB pendrive is ok, but I read that, after the creation on the USB pendrive is updated by Windows by the “System Volume Information”.
To avoid this update of the USB pendrive by Windows, REMOVE your USB pendrive at the END OF the “Fedora Media Writer” which create, and verify the pendrive.
Do not eject the pendrive with the appropriate Windows function that you say “Now you can plug off your USB key”.
Surely it can be dangerous, but it’s the only way that I have found to avoid the Windows updating !
We can ask to Fédora Developers Community to take into account this Windows specificity.
Note that the Fedora 38 installation is very short : 10mn !
I just had the same issue (the same warning as in post 1 by Bernd Arnold).
If I select the third option ~troubleshooting, i am able to login into the liveUSB and see F38 fine.
Note that sudo fdisk -l shows that

so indeed some Microsoft data is in the way.
[corrected] Does anybody know whether it is the reason of the error msg reported in post 1 above?
Seeing partitions labelled Microsoft basic data for the install USB is normal. In linux you can mount the Fedora-Workstation-Live-x86_64-39-1.5.iso as a “loop” device:
% sudo fdisk -l /dev/loop0

The USB key should have the same partition structure.
Buenas días /tardes/noches con todos, soy un principiante en Fedora pero no en Linux, también se me presento este error, me quedaba al 0004.0% y no pasé la primera vez, sin embargo para este proceso había descargado primero el mediawriter y luego el iso, en esta segunda ocasión no he cambiado el usb como todos indican, solo use el “mediawriter” con el mismo PENDRIVE pero ya no use la imagen sino que use la opción de descargar desde el mismo “MEDIAWRITER” y ahora estoy Instalando Fedora 40 con normalidad, en el mismo PENDRIVE/USB. INTÉNTELO. Gracias.
