Doesn't see flash drive in bios. kali linux save data after reboot?

Question

BIOS

Installed on a flash drive "USB SANDISK Ultra Dual drive 32GB" ( https://www.citilink.ru/product/fleshka-usb-sandis...) Live CD kali linux, run from HP laptop. At first, the BIOS did not see the flash drive at all, but it was displayed in the "launch from file" section. I didn’t see a Kingston flash drive with an archer either. I turned off fastboot, Secure boot in the BIOS, I began to see the archer, but I did not see kali. Solved the problem in a strange way. I realized that boot devices are requested only at startup, so I started it with a laptop archer. After the launch, I changed flash drives, and supposedly started from the archer, but from another flash drive. Earned. Further, I ran into a problem that kali saves all data after a reboot. I recorded the image on a USB flash drive using Rufus, allocated 8 GB for the Persistence section. I run Live CD in GRUB, without Persistence mod, and after reboot all data is saved. Previously, I set the password to root, when the system starts, it immediately enters the kali user, however, then I can enter the previously password-protected root. Question - what is the reason for this, and how to fix this problem?

Answer 1

and how to fix this problem?

Very simple - stop torturing the animal. Kali is a distribution for professionals. If you are not able to deal with it, it is still too early for you to work with it (and does it even make sense? Are you an information security specialist?)
The laptop does not see the flash drive for a very simple reason - it has only EFI, and the flash drive has MBR :) (And if you don’t understand what I said now, it’s definitely too early for you to take on Kali)
