I checked the Android-x86 downloads list. It contains .iso files for Laptops. I want to install Android on home PC.
It all depends on the device where you're going to install this Android port.
If you access the download page of the Android-x86 Project, you'll find a short description for every available ISO to point you out onto the proper download.
Assuming that you're out to try the latest, Android-x86 4.0-RC1 live and installation iso:
for ASUS Laptops/Tablets <-- Best bet if your referring to a desktop PC or a Laptop.
For the purpose of completeness,
Here's a small description of the Android-x86 Project - Run Android on Your PC:
This is a project to port Android open source project to x86 platform, formerly known as "patch hosting for android x86 support". The original plan is to host different patches for android x86 support from open source community.
I suggest you try the latest 4.0 release candidate.
See the release notes and try the closest matching. I was lucky and my unsupported Netbook ran it. YMMV though. It's a question of CPU, GPU, chipset and screen resolution.
It's a live CD so you can just try without installing it first.
