Two things you should try. 1. If not already, remove rhgb and quiet from the kernel boot line so you can see the boot messages, and the final error that is throwing you into the grub prompt. 2. After getting the system up and before you reboot, look in the journal to see what is reported about the issue causing the drop to a grub prompt. journalctl -b will show the last boot. That you have to set the root manually suggests to me that the boot record isn't pointing to the right place. Correcting this is different for uefi and mbr, so you'll have to tell us which method you are using. I don't see how this could happen from an interrupted dnf update unless the disk was somehow corrupted, but it is what it is. Maybe you should try running a non destructive file system check to see that the file system is intact. If you have a rescue cd or usb, it is a lot easier to boot it and do these kinds of things from a separate fully functioning system. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
