Hey, you got a HP laptop with installed Win8.1(64bit, UEFI, GPT), decided to set next to him on the same hard disk Kali Linux(64bit). Using Rufus mounted on the stick the iso and turned off Secure Boot and Fast Boot in BIOS or setting the pass normally to install GRUB. Climbs error: Executing 'grub-install dummy' failed.
This is fatal error.
Found online solution where you have to run Kali Live USB, and enter terminal code: https://forums.kali.org/showthread.php?41256-Execu...
But an error is displayed:Installing for x86_64-efi platform.
grub-install: error: cannot open `/boot/efi/EFI/kali/grubx64.efi': Input/output error.
