How are you trying to boot with the floppy. What Floppy? If you want to boot Windows 2000 you have to use the 4 boot disks not the ERD. Boot from your CD it is faster.

Does the keyboard work while you are booting? Logitech has had issues with their drivers and Windows 2000 & SP2. I don't know about the keyboard but the mouse drivers have had big issues in the past.

Do you have floppy boot enabled in your Bios. I think you have to enable other devices also. It is usually an couple of lines down.

Make sure everything is enabled in Bios also. IR, USB all IDE etc..

Well hope some of this rings a bell! :-)
