Added a Fedora 37 and Fedora 38 installations on separate drives to a
Windows system. Default boot is the Windows 10 system. Using the boot
menu gets me to grub which can boot the system of my choice.
When the Fedora 38 install goes to sleep it doesn't come back to Fedora
but boots to the Windows install. ...
when the box initial was installed with windows *I* guess the BIOS boot option still point
to windows.
point it to Fedora and run
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
to include Windows into grub's bootmanagement (keyword: os-prober)
No ?
