I am Dave, I will help you with this.
You cannot install Windows 11 on that drive from an ISO, you need to create a bootable USB, then boot your PC form that

Select the second option (Create Windows 11 Installation Media)
Then run the media Creation tool that downloads and select the option to create a USB
Wait for that process to complete.
Then, Boot your PC from the Installation Media you just created (change Boot Order in your BIOS) to begin installing Windows 11
Since you previously had Windows 11 installed and activated on that PC during the installation process skip the steps which ask for a product key and select the option 'I am Reinstalling Windows 10 on this PC', and activation will not be an issue, your PC will have a digital entitlement stored on the Microsoft Activation Servers
