Hay all of You,
Thanks for help and answering. The problem is simple . The fresh install of Fedora 41 no problem. The menu of the booatloader is the problem and I do understand this is kwown. (See mail Camina Shell)
After the succesfull fresh install I get the bootmenu : First Kernel install version , so no second Kernel update,rescue mode and Windows choice possibility. So far so good.
When rebooting the system no bootmenu : Just Fedora is booted no choice menu ; That is all. See below the BIOS settings on this machine.
Boot mode is set to : UEFI with Legacy OPROM ; Secure boot : OFF
Legacy Boot :
Hard drive
CD/DVD/CD-RW Drive
Network
UEFI Boot :
Windows Boot Manager (CT1000BX500SSDI)
Fedora Boot (CT1000BX500SSDI)
You can understand the user can open the BIOS and made the choise Windows Boot or Fedora Boot but this a dangerous procedure and not very elegant.
So the final question is : Where is GRUB ?
And now , how farther ?
