Disable secure boot - both in BIOS and Fedora - get grub to come back - Fedora 41

I just had reinstalled Windows 11, and that had changed my default boot in BIOS to Windows. I tried changing it back in BIOS to Fedora so that I could boot again from GRUB, but it refused to save with Fedora as the boot option. So I reinstalled Fedora… but that required me to reinstall the Nvidia drivers. I couldnt find a walkthru that actually worked, so I posted here

I was told to use the walkthru here Howto/NVIDIA - RPM Fusion but they said to make sure to do Secure Boot setup first. Thinking that was something I had to do to get the Nvidia drivers working, I asked where the walkthru to do that was, and was told to go here.
Howto/Secure Boot - RPM Fusion

Got all that setup and working… but now when I boot, no GRUB shows up, and it boots straight into Fedora. I have tried spamming Esc - then F9 for Boot menu, or F10 for bios. I disabled Secure boot. No change. F9 boot menu, and went to Windows. It gives me a blue screen and 3 seconds before reboot. I press any key, but no option lets me boot into Windows. Everything reboots and goes back to Fedora. How do I disable Secure Boot, get grub to come back when Fedora boots. At this point I can’t even boot into my USB and reinstall everything.

I have tried searching for this as well, but I am not finding how to fix it.

after disabling secure boot in bios i was able to boot back into windows usb. so i will reinstall everything.

In order for GRUB to always display the boot entries at startup, you can run the following command from Fedora:
sudo grub2-editenv - unset menu_auto_hide.
