|"PXE-E61 Media Test Failure, Check Cable"|
Your computer is attempting to boot off a network. No network is being found so you're being prompted to check the network cable. It could be an indication that your hard drive has failed. Check the BIOS to make sure the HDD is still being detected & then check the boot order to make sure it's configured properly. Disable the network boot.
If you changed anything inside the case, make sure all cables are connected correctly & securely.
I'm curious why you felt you needed to do a hard install of Kali rather than just running it directly from your USB stick? Isn't that how Forensics & Penetration Testing is usually done?
