Hello,

If you modified /etc/default/grub prior to the upgrade, then it might be the reason

I can recollect my own fresh installs from ISO, in certain cases they never booted by normal meanings. Wrong partitioning, missing bootloader, etc.

I am not sure what help you might want in this case. If it is a testing system you might either re-install and see whether the issue re-occurs, or troubleshoot the boot process typing booting commands manually.

Ahhhh, after spend times 24hr, now I can fixed this issued.

The issued happending when running VM on some cloud software, so "grub2-install {device}" can solved the problem after updated the new version of "grub2-common".

#fresh install from ISO and execute these command

reboot # Ensure new installed from ISO should working fine.

dnf update grub2-common -y
grub2-install /dev/xvda #this command should return "no error"

reboot # Ensure new "grub2" should working fine.
