Every BIOS is different, so the exact instructions will differ from computer to computer. To re-enable this feature you need to restart your computer and go into the BIOS (Delete, F2 and F10 are common keys to enter it, but check your computer’s manual for full instructions). Practically any processor capable of running Windows 7 or Windows 8 has this hardware feature, so that problem is likely to be that it’s been disabled in your computer’s BIOS. This feature is designed to stop malicious code from running on your computer, by marking some bits of system memory as non-executable it means that if a virus infects this part of RAM, your processor will refuse to run it. If you get the ‘Processor not supported’ message, it’s because your CPU needs to support Execute Disable Bit. You should now be able to install Windows 10. Follow the wizard through as before and re-create the installation media. Right-click it and select Run as Administrator.
To change that, download the Windows 10 Media Creation Tool and locate it on your hard disk. The second option is that you’re trying to install Windows from a USB flash drive or DVD, but you created the installation media without the proper permissions.
