Need Help Bad!!!

I'm trying to get my computer up and running again and it was running Windows 98SE. I don't know what happened to it, but I needed to reinstall Windows SE and I don't have the disk for it. I have the product key code, but not the disk. I acquired the disk and I did a format c:\ to clean the c: drive out. I didn't have a boot disk so I downloaded one on bootdisk.com. When I turn the computer on, the bootdisk is in the floppy. The computer tells me that it searched for the boot from floppy and said okay. Then it says to remove any disks or media and press any key to restart. I did just that and and then it said search for boot record from floppy - not found, boot record from CDROM - not found, boot from IDE - OK. Then it says Invalid Disk, insert disk and press any button. I tried to insert the Windows 98SE CD, but that don't work. I tried to put the start-up disk back in and pressed the button, but it keeps telling me the same thing. It's like a never ending cycle. I don't know anything about the Bios. I don't know what the settings should be. I only know how to change the boot order. I don't know what to enable or disable in the Bios. Can anyone help me?
