FristiLeaks1.3 - CTF Walkthrough - Boot-To-Root

Hello. I watched your walk through and would like to give it a try myself. Only problem is, is I cannot get the VM to get an IP address. Long story short, I created an internal network in virtual box and made it a dhcp server. I know that part works as I can log into my kali vm and a windows vm and verify that I have an IP addresses. But when the fristi vm opens it says it cannot get an IP. I’d like to log into that vm to see what’s going on but I do not know the username and password. And I am not going to use bridged or NAT on this vm. Any help would be great. Thanks.
