I’ve found a mistake in the book. In Chapter 2 , exercise 2-3 boot options – you presented an answer to press ‘e’ when boot from live USB. As I checked there is no ‘e’ option when you boot Kali Linux from Live USB as there is no GRUB boot loader (as on permanently installed Kali Linux). There is a TAB option which allows you to edit the menu items.
Could you tell me how you were able to have this ‘e’ option in the Live USB as there is no such option in Kali Linux ISO downloaded from your site ?
