Can't boot other Systems

[Samir16]

As I said on my previous post I was trying to dual boot Windows 10 and Kali Linux and I didn't get good help 😑. Today please answer my question correctly and don't talk about another topic please. I'm trying to boot to the Kali installer from my flash drive but whenever I try to it just boots back to the hard disk. but When I boot Windows 10/8.1/8 setup from a flash drive or a DVD it boots into it perfectly so why do other systems like Windows 7/vista or Linux installers don't boot. I think this thing have something to do with the boot loader of Windows 10 on my Hard disk. so how can I boot other systems? please give me serious help don't simply say you can't.

You have already been told that HP does not provide detailed Linux support ...

So, continuing to post over and over about this problem is NOT going to change that.

Thanks for your reply but I totally understand that HP doesn't give support for Linux but in this topic I'm not talking about that my problem is that I can only boot Windows 10/8.1/8 setups and OS but I can't for other systems I just wanna fix that I have nothing to do with Linux in this topic.

Modern PCs generally come with UEFI established and that means that one or both of the following BIOS/UEFI settings are enabled:

1) Secure Boot

2) Disable booting from portable devices

You have to change BOTH of these in the BIOS/UEFI settings to be able to boot from anything other than the internal drive.
