Do you get an error, do you end up in Windows, or ...?  Did the problem occur after using Windows?  Have you checked the BIOS settings?

Obviously, my subject line was not adequate. The menu I need to create an entry in is the bios boot menu.  I have a UEFI system, so I think I will have to use efibootmgr.  So far I have only succeeded in getting into the F33 system using rescue mode and a chroot. My attempt at creating an entry from there using efibootmgr actually put an entry in the menu, but when I tried to select it, a not valid entry error was reported, and I had to reboot. What I need is more guidance than what is available in the man page for efibootmgr.
