|Well, the first step is purchasing a copy.|
When you have done that, post back.
Since Microsoft no longer sells Windows 95, the best way to obtain Windows 95 is through eBay.
Try to pick up a new copy; you don't know the condition of used software that is 16 years old. I also recommend CD ROM if your computer can take it because floppy disks corrupt over time and no longer work. Plus, CD install is much faster than floppy.
The link below is to all the new copies of Windows 95 currently available on eBay.
