I was trying to install NVIDIA drivers and I read that I needed to disable secure boot. I did so and now it boots to windows 10 by default and I have to press f9 to get the option to boot Fedora which then brings up GRUB.

I read that I have to make sure that ‘OS Boot Manager’ is at the top in Boot Option and it is -

If depends on your disk layout.

Can you boot to Fedora, then post the output of
sudo efibootmgr -v, lsblk -f here?

Please do not post screenshot of text contents - it is hard to read and not searchable.

Would you please copy and paste them as codes (click the </> button in the edit tool bar).

I hope this works better

Yes, it is much better.

You have two “Fedora” listed under efibootmgr. I am not sure which one is the correct one for you. So you can try them one by one to find out.

You can change to boot 1st Fedora by:
sudo efibootmgr -v -o 0

You can boot the 2nd Fedora by:
sudo efibootmgr -v -o 2

The above change is permanent until your UEFI boot order is reset.

why do I have two fedora listed there? This is the first time I’ve installed it. I’ll see if it works though

thanks

When you run efibootmgr -v, it also show from where does the boot entry is detected.
