I decided to play Kali Linux on my old laptop, but the "installer" can't find the right hard drive to partition. I only see the installation medium.
Since Kali Linux is for professional pen testers and you are one yourself, you will surely find out with an online search 👍
If you are looking for a desktop Linux for office, music, video, surfing the net, etc., then take a different distribution like
Linux Mint
openSUSE
Manjaro
Take a look… Hardware? Hard disk?
