I'm trying to dual-boot Windows 10 and Kubuntu but since I tried setting grub as my boot manager with bcdedit /set "{bootmgr}" path \EFI\ubuntu\grubx64.efi
in Windows' BCDEdit, my screen is Black until I log in to Windows (no BIOS POST or Grub menu). I just found out that I have to grub.cfg files. One in /boot/grub/grub.cfg on my / Partition and one on an unnamed FAT32 boot partition under \EFI\ubuntu\grub.cfg. I don't know which on is read when booting, I don't know if I should delete. Also if I'd run update-grub would only one file update? Maybe the one I don't need?
If you know what's going on here, please help me because I don't.
Thanks in advance!
