Good afternoon,
Yesterday evening, a third IT grad student (PhD candidate specializing in cloud computing) came to help with this problem. After I showed him the log file and the discussion in this list, we booted, and of course it failed and dropped us into the dracut shell. He examined the rdsosreport.txt file. He ran "fdisk", but he typed too fast for me to see the whole command line. He responded 'y' to a few things, but it was too fast for me to see what. He then exited the dracut shell (I did not see him enter any "mount" commands.), and hit the hardware reset button. The system booted up successfully.
Later in the night, I shut the system down for the night. This morning it booted up fine. Early this afternoon, I did the weekly "dnf upgrade". Since the kernel was among the things patched, I shut the system down, and then booted it back up again. It booted successfully. I'm now willing to say the core problem is solved.
There are related questions that remain unanswered; I'll open new separate topics on them in the next few days. I see 10 list members (plus 4 off-list helpers) participated in this topic. I knew when the problem surfaced that this would be difficult. It turned out much more difficult, tedious, and time-consuming than I anticipated. But y'all got me through. Thank-you very much.
Bill.

Good afternoon,
This is an f24 system. I just (about 1pm US mountain time) completed my weekly "dnf upgrade", and I saw no hint of failure or trouble. But when I shut down the system, and then powered back up, the boot failed. The grub menu looked ok. The blue-and-white bar at the bottom of the boot screen did go most of the way normally. But it never got to the log in screen. There was some text being displayed, but I have no way of capturing it, and I don't remember what it said.
I'm no sys. admin. I have no idea what to do. Please help. (I'm using a windows 7 system for this e-mail.)
Thank-you in advance. Bill.
