I have created my bootable flash drive as usual, with Fedora Media Writer and I can actually see the type of boot screen (Start Fedora, test the media, troubleshooting) and after selecting any of the options I see a frozen black screen. No error messages and I can only reboot by pressing the power button (Ctrl+Alt+DEL don't work).

It is the same with my Dell notebook and on a Frankenstein desktop that I have at work. The result is the same for Workstation and NetInst.

Dell Inspiron 15 5567 CPU: Intel Core i7-7500U

GPU: AMD Radeon R7 M445 (2GB GDDR5)

Display: 15.6”, Full HD (1920 x 1080),

IPS Storage: 1000GB HDD

RAM: 8GB DDR4, 2400 MHz

I have a Bz ticket open here: https://bugzilla.redhat.com/show_bug.cgi?id=1753033

And a thread at ask.fedora (https://ask.fedoraproject.org/t/unable-to-boot-flash-drive-to-test-fedora-31-beta/3410) where I:

Have tried 2 different USB sticks
Used Fedora Media Writer, Rufus and dd to create the media
Checked the hash of the downloaded image of F31 Beta
Conformed that F30 and F30 respin are starting correctly from the same USB sticks
