Thanks folks.
Disabling UEFI mode did the trick,
though I do not understand why it was necessary.
I thought that recent Fedora DVDs worked with both legacy and UEFI.
The Fedora-WS-Live-39-1.5 DVD does have an EFI directory.

I didn't get a grub menu until disabling UEFI.

Fedora can install on either legacy BIOS mode or modern UEFI. But when it installs on UEFI systems, it creates a special partition mounted on /boot/efi. If you boot a system which was installed in BIOS mode in UEFI mode, it doesn't see that partition and won't boot.

If you want to run Fedora in UEFI mode, I am relatively certain you have to reinstall (but I could absolutely be wrong). When I got a machine which supported UEFI, I initially turned off UEFI and Secure Boot because I'd heard horror stories about them with Linux. When I changed it to UEFI, I couldn't access my Linux installation. But since I had a backup of my home directory on another machine, I just nuked it and reinstalled, then restored my home directory.

I've actually set up my Linux machines so that they mount /home on an NFS file server in my home office. I can nuke my desktop and reinstall it in less than 10 minutes with a kickstart, and my home directory is unchanged. Makes it a lot easier when I do the inevitable "oops" and screw up my desktop.

As an aside: Using KVM virtualization has eliminated a lot of those "oops" moments. If I want to test software or something, I spin up a VM and test it there before I do it on my actual "production" workstation.
