Kali Linux

[CP34]

I am trying to install Kali Linux on my laptop but when I choose the USB or CD to boot from it always says "selected image did not authenticate". I have followed the instructions on the Kali Linux website exactly. I have tried both USB and CD neither have worked. I've tried multiple USBs I don't know what else to do.

The copy you downloaded is corrupt, download it again on a fast connection with no interruptions and it should work.

Ok I have downloaded new copies without interruptions. Will my USB be corrupted or is it still ok to use the same one as long as I clear it? When I enter the USB into my laptop I cannot access it because it says it says it is not formatted.

Couldn't hurt to reformat but Kali should do that anyway on the install but just to be safe wipe the USB then install Kali.

I reformatted it and tried a different copy the same thing happened. So I reformatted it again and used a different copy and when I selected to boot from a USB it said "selected boot has failed"

Let me rephrase that it actually says "The selected boot device failed" I have turned off secure boot and turned on legacy boot and it still won't work. Ok i just went into the bios and chose reboot from USB it said device failed so then I went into the boot options and chose my USB this brought me to a screen that's all black and had "Missing operating system" in the top left corner
