Kali Linux doesn't start properly?

Is an old laptop from me, it was just under the bed.

What can I do to make it start?

Windows 7 doesn't start completely either, it hangs when starting.

Rather use Linux Mint xfce or Xubuntu for older hardware.

Kali Linux is only for professional pen testers and with your question you show: you are not one of them. So let it be.

Kali Linux is planned as a live version.

Kali Linux is relatively slow, just until the system is ready to start it can easily take 5 minutes, even with newer computers.

You won't have much fun with it on your old laptop.

Windows 7 doesn't run particularly well there either.

There are distributions like Linux Bodhi - the old laptops run really fast again.

It is there. Shall we read it to you?
