Hello all. I am starting out my pentest/hacking career and I am installing Kali Linux on my Windows 8.1 PC for a dual-boot. The installation has been going well and it has been installed on the system. It is now installing GRUB, and my problem is with the GRUB installation. It has been stuck in the same position (about 60%) for a good 30 minutes now with the command 'running "update-grub"'. I don't know if I am just being impatient or not but I would appreciate your thoughts.
