firmware needed and errors during the install process of KALI 2020.2

Hello everybody,

I have an issue installing Kali Linux 2020.2 and as i did not find any solution which works on google and as i definitely don't know how to fix it then i decided to creat a thread here. The error message appears during the network hardware detection,

I quote:

Some of your hardware needs non-free firmware files to operate. The firmware can be loaded from removable devise such as a USB stick or floppy.

The missing firmware files are:

regulatory.db
iwlwifi-8265-36.ucode
iwlwifi-8265-35.ucode
iwlwifi-8265-34.ucode
iwlwifi-8265-33.ucode
iwlwifi-8265-32.ucode
iwlwifi-8265-31.ucode
iwlwifi-8265-30.ucode
iwlwifi-8265-29.ucode
iwlwifi-8265-28.ucode
iwlwifi-8265-27.ucode
iwlwifi-8265-26.ucode
iwlwifi-8265-25.ucode
iwlwifi-8265-24.ucode
iwlwifi-8265-23.ucode
iwlwifi-8265-22.ucode

If you have such media available now insert it and continue.

I have never had this issue before on this laptop (on which i had Kali 2019 for a long time...) It's a Lenovo T480. (I5)
I would like to add that i have tested the USB live stick on which was running the install. This one has worked perfectly on an other laptop which means i did not have any of this kind of errors.

Please, could you help me to fix this problem.

Thank you !
