First SATA setup soon - quick question

[No-One]

I should finally be moving away from IDE this week. I'll just be using the new drive as a single drive setup. Is a floppy drive needed for windows installation, or is that only for raid setups? I'm using a MSI K8N Diamond motherboard.

The reason I need to know for certain is that I have no floppy drive and my power supplies floppy cable doesn't work. So I may need to buy a new PSU too. Really need to be sure.
