I tried to upgrade from Fedora 33 to 34 beta on two laptops.
On #1 (Lenovo Thinkpad X230), which has a dual boot with windows 10, the upgrade removed Fedora from the grub boot screen, which now only show windows 10 as the only option.
I have tried to fix grub using a chroot from a live usb, but so far only an error message: “… is /dev mounted?” (yes, it is…)
On #2 (Lenovo Thinkpad W530) the upgrade went well, and I can boot into Fedora 34 - but only to be met with a login screen that continuously flickers after a few seconds, to say the finger print scan is not valid (in my language, which is Norwegian) under the password input field, making it impossible to log in.
I have logged in using a terminal (ctrl+alt +F2) and will upgrade there until (I hope) this issue is fixed.
Jus to let you know
