Created attachment 1328801 [details] screenshot Description of problem: create an installer using "dd if=Fedora-Workstation-Live-x86_64-27-20170920.n.0.iso of=/dev/sdb" with usb stick,then boot the installer,the installation failed,as shown in the attached screenshot. f26 mediawriter dosen't works well(#bz1493899),so I choose to create the installer using dd Version-Release number of selected component (if applicable): 20170920.workstation How reproducible: always Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
It seems that this only affects workstation-live not server.iso,though you are unlikely to create the server.iso installer using mediawriter.
Proposed as a Blocker for 27-beta by Fedora user lnie using the blocker tracking app because: This affects the Beta_Release_Criteria: Release-blocking live and dedicated installer images must boot when written to a USB stick with any of the officially supported methods.
It's working fine for me: $ sudo dd if=Fedora-Workstation-Live-x86_64-27-20170920.n.0.iso of=/dev/sdb bs=16M status=progress oflag=direct $ sudo cmp Fedora-Workstation-Live-x86_64-27-20170920.n.0.iso /dev/sdb cmp: EOF on Fedora-Workstation-Live-x86_64-27-20170920.n.0.iso $ sudo checkisomd5 /dev/sdb Press [Esc] to abort check. The media check is complete, the result is: PASS. It is OK to use this media. I booted it and verified checksum over both bios and uefi, all ok. When using dd, you must be very careful to not use in over a mounted partition. Also, if you mount the partition after writing, it might also change filesystem metadata, which in turn fails the mediacheck. It's a very common mistake, I attribute your problem to it. If you can't make it work, ping me and we'll look at it.
Have you tried to use the created installer? I have created the installer using dd carefully,the media check passes, but it's still unable to do installation with usb stick.please see the attached screenshot.server.iso works fine,but workstation dosen't

Yes, it works fine here. Not sure what went wrong there. One thing confuses me - you're talking about creating USB sticks, and then you're attaching VM screenshots. So which one is it? USB sticks should be tested with bare metal. VMs can be booted from the image directly, just mount it as DVD.
My fault,I have used a tiny tricks here : I insert the usb stick to the host machine,then add it to the virtual machine using virt-manager's add-hardware option,and add it to the boot menu. It works well all the time,not sure what went wrong this time.
Sure, that should work, but it's very easy to get the stick automounted and therefore have checksum changed, or something else can go wrong. If you have troubles with it, always also try a proper way of booting to check whether it's a real problem or just something in your particular process.
