Doubs on Kali and dual boot with Arch

[DarkPassenger]

Hello everyone.
I have ArchLinux installed on one partition and I wanted to install Kali encrypting another partition of 250 GB.
although crypto partition, Kali only recognizes the entire HDD and then I would definitely eliminate ArchLinux.
I wanted to know if you know how to dual boot but, in any case, I can also reinstall everything. Start by installing Kali on an encrypted partition and then install ArchLinux?
I want to start using Kali, I'm studying for the penetration testing and I wanted to know if it was safer on an encrypted partition or Kali Kali simply virtualized?
It's possible configuring Tor automally?
You can use it as a normal desktop version or it is slow?

I prefer Kali rather thank BlackArch for guides and for this forum!

Thanks guys

i don't know answer on this questions, but i can recommend you little to investigate.
try first to install Kali on system (encrypted). Then if it is all ok, mean you can boot in Kali normally
then with gparted shrink (resize) partition and leave it blank those space
after that install ArchLinux ( don't install any grub, lilo) and when you finshed installation
boot in Kali and run "updat-grub"
it should be all, but i have to wrote that i am not sure how those encrypted partition acts when
you resize it.

"It's possible configuring Tor automally?
