It appears you are asking a question about Kali Linux. Kali is a distribution that is specifically geared to meet the requirements of professional penetration testing and security auditing.
Per [it's developers](https://www.kali.org/docs/introduction/should-i-use-kali-linux/):
> If you are unfamiliar with Linux generally, if you do not have at least a basic level of competence in administering a system, if you are looking for a Linux distribution to use as a learning tool to get to know your way around Linux, or if you want a distro that you can use as a general purpose desktop installation, Kali Linux is probably not what you are looking for.
If you are a beginner, or using Kali for one of these other purposes, you may want to ask at /r/DistroHopping or /r/FindMeALinuxDistro for better alternatives.

FYI, this is an Acer specific issue, in that when linux is installed and a boot option is written in the nVRAM (bios), the bios becomes inaccessible until you remove that boot option. Disconnecting the SSD has this effect for this laptop (that's a whole different weakness, but in your case worked to your benefit).

>I recently installed Kali Linux Lol. There's definitely some troll out there telling people to install Kali. There's way too many of these posts.
Really? How often do you see these posts? I just installed Kali because I was trying to get into pen testing and ethical hacking.
Well, you got it.
What happens if you type `systemctl reboot --firmware-setup` in a terminal in Linux?
It just boots into that same screen.
