Well hello there, I have a little problem with my dualboot setup.
So I decided to dualboot Windows (for gaming-puposes) and Fedora (for everything else), and I also decided to give them separate drives - a 120GB SSD for Fedora and a 500GB HDD for Windows.
So I first installed Windows on the HDD (making sure to boot the installer-CD in UEFI-mode), then I installed Fedora on the SSD (again, making sure I was booting in UEFI-mode) - btw I used the auto-partition feature of the installer - and rebooted.
On first glance everything looks fine - GRUB gives me the possibility to boot Fedora, Fedora Rescue Mode, as well a "Windows Bootmanager"
Booting Fedora works fine but if I choose the Windows bootmanager, I get the following error message:
error: file '/EFI/Microsoft/Boot/bootmgfw.efi' not found
error: you need to load the kernel first
However, if I set my motherboard to load the Windows Bootmanager directly, Windows starts up fine (doesn't give me the option to start Fedora though), so I assume it's a problem with my GRUB.
P.S. my storage mode is set to AHCI - I somewhere read that might make a difference...
