I installed Windows 11 on my 512 GB SSD drive. That worked out fine. Then I installed Fedora 42 KDE Plasma 6 on my 1 TB SCSI drive, /nvme0n1. Now the machine (AMD-64) boots right into Fedora/KDE, without any pause from the grub menu. and no option to boot Windows.
I can mount the windows partition, which is on /dev/sda2, and see all the files. But I can’t boot into Windows. I read a similar topic on Ask Fedora, so if it helps, here is the output of
$ sudo efibootmgr

The command “os-prober” produced no output, but terminated with an exit code of 0.
I went through the exercise of reinstalling Windows, which booted only Windows, then installing Fedora 42 again, and could then only boot Fedora (with no pause for a grub menu). Same result as originally.
It seems that when I installed Fedora 40, the installer recognized my pre-existing Windows installation. Any suggestions? I’d be glad to post command output from anything you suggest. My fedora partitions are as follows:
/dev/nvme0n1p3, subvol=root on / (btrfs)
/dev/nvme0n1p2 on /boot (ext4)
/dev/nvme0n1p1 on /boot/efi (vfat)
/dev/nvme0n1p3,subvol=home on /home (btrfs)
I installed using the the the regular anaconda installation program, using automatic partitioning.
Thanks for your help.
