[SOLVED]PC suddenly stopped booting after reboot command

[SOLVED]

Mageia 9.
My server pc suddenly today stopped booting into graphical desktop. After reboot, the spash sceen is shown a few minutes but after that goes to a terminal window and shows "welcome to emergency mode". A few options are given there but I can login as root. However, the network connection does not start. "journalctl -xb" shows >1600 lines which does not give me any clue to what is broken (unfortunately I'm not an expert). However it shows a some error lines marked with red. I believe the info is there, but I don't know even how to export what's displayed to some external media.

Please advice what steps to take to, if possible, repair the system. I spent many years on this server.

Last two photos from journalctl -xb. The first photo in this post shows the last output that exists. Maybe the last one shows what happened?
Would appreciate any help!

At least the mounts for /media/win_c, /media/win_d and /data failed.
The warnings about fedora-loadmodules and var_lib_nfs can be ignored, those are irrelevant.

When in emergency mode, best check the output of df or mount and then try to mount your local filesystems from /etc/fstab one by one.
For those that fail, run an fsck once they are not mounted.

Thank you very much for the reply.
However, yesterday afternoon I decided not to spend more time on troubleshooting since I had a one month old working disk image. With it I restored the system and after restored the data lost from another backup.
