Android X86 install and runs perfectly well on Dell Laptops, You can run it 'live' from a USB stick or DVD, to see how well it runs on your laptop. But, to install it you'll need to reboot and choose install from the Android boot menu. DO NOT attempt to partition the hard disk, as Android has it's own partitioning scheme that's very different to either Windows or Linux. I had better results using Lineage OS (also so on the Android X86 site)
The current version is based on Android 8.1, and there's a beta of Android 9. It really is full Android on a Laptop. Don't worry about a lack of touchscreen, the Laptop's touchpad works just fine.
