Computer Hope

I have a Sony Vaio model number PCG-7134M.
It was gifted to me and has a Windows 7 product key. I wanted to upgrade it to Windows 10 and searched on YouTube on how to do this.
I downloaded Ventoy and created a ISO file on a Flash drive. I also downloaded Windows 10 64 bit.
I followed the instructions I was given and when I turn on my laptop, it loads Ventoy and comes up with an error message saying "No ISO file found (press enter to reboot) and when I reboot I get the same message.
If anyone can help me I would greatly appreciate it.
Thank you

Why use Ventoy ? ? The media creator tool works fine...
