So here is the problem: I started up windows and created a partition. I restarted and tried to install Fedora30 from a USB. All went fine until, at the end of the installation process, there was an error message saying: booting manager (or something else .. I forgot) does not work due to something with kernel. When I was asked if I wanted to continue the installation of Fedora anyway I clicked 'no'. Then I restarted the pc and we'll... Found this screen:
System BootOrder not found. initializing defaults. Creating boot entry "Boot0009" with label "Fedora" for file "\EFI\fedora\shimx64.efi"
Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.
I tried to start Fedora from the USB again, but it does not work. When I start the boot menu no USB shows up. I was thinking of using another USB stick or even a CD to try and install Fedora correctly. So I found another USB and put Fedora on it and yes it is recognized, but I still cannot boot from the USB, for the same screen shows up saying System BootOrder not found...
Any other ideas and tips? Is there maybe a command line to start Windows from Grub? Thanks for your time and help, Rafael
