I try to dual boot Windows 10 and Kali.
At the point where i need to install GRUB bootloader I get following error:
"Unable to install GRUB in dummy
Executing 'grub-install dummy' failed.
This is a fatal error."

I tried this: https://wiki.debian.org/InstallingDe...CIe_SSD/jessie
At the point where I need to do this: "grub-install --target=x86_64-efi /dev/nvme0n1"
I get the error: "grub-install: error: cannot open '/boot/efi/EFI/kali/grubx64.efi' : read-only file system."

To my System:
- Lenovo ThinkPad Yoga 460
- 8 GB RAM
- Intel Core i7-6500U
- 256 GB Solid-State-Laufwerk, SATA3

Kali:
Kali 64 Bit Version: 2016.2
Win32 to create USB

Booted in UEFI only, Secure Boot Disabled

Do you have any idea what I could do?
I hope this is enough information.
