Error

I get an error error when trying to install Fedora 24 on a new computer I had just built. I choose Test this media & install Fedora 24 from the boot screen and then get the following error:

... Fragment count: 20 Supported ISO: no Press [Esc] to abort check. Checking: 004.8% The media check is complete, the result is: FAIL It is not recommended to use this media. [FAILED] Failed to start Media check on /dev/disk/by-label/Fedora-WS-Live-24-1-2. See 'systemct1 status "checkisomd5@dev-diz-by\\x2dlabel-Fedora\\..."

[ 11.224174] dracut: Refusing to continue [ 11.915103] reboot: System halted _

Testing

I tested the following to try and find the problem.

  • the method I used to write the iso image to the flash drive
  • the flash drive
  • the computer I was installing on

However, I did some tests and found that none of those three things were the issue. Here's what I did to find that out:

I downloaded an iso image of Fedora 24 and tested it in a virtual machine, where it worked perfectly. Using a MacBook, I followed the instructions on the Fedora Project Wiki to write the iso file to a flash drive by using diskutil. Using my Windows 7 partition of the MacBook, I wrote the iso image to a second flash drive using SUSE Studio ImageWriter and those same instructions. I then tried both flash drives on my newly built computer and the MacBook; all got the same error listed above.

Choosing Install Fedora 24 at the boot screen instead of Test this media & install Fedora 24 causes the installation to freeze at some fingerprint authentication daemon.

Question

Why would it work in a virtual machine but not on a real computer, assuming iso write method, flash drive, or computer?

I succeeded by using a different computer to write the iso image to the flash drive. Apparently, switching partitions on the same computer is not the same as using a different computer altogether.

The reason the media check always fails at 4.8% exactly is that , when you insert a USB into a windows machine, it adds a file to that USB to help with searching and indexing external drives (a practice I disagree with; reading an external drive shouldn't modify it unless explicitly permitted to do so).

Anyway, look into"WPSettings.dat" and "System Volume Information" folder. You can disable it, but it may be technical. Solutions can be found online.

  • i compared usb with iso, both mounted, with diff - r, and it showed nothing, means no diff. Commented Apr 8, 2023 at 6:14
  • i tried dvd-rw and it is ok Commented Apr 8, 2023 at 8:11
