URGENT-Installing Win98SE on top of W2K

Hi Everyone! Hope u can help…
Have recently installed W2K on Win98 o/s, but have just realised that in order to run one of the programs I desperately need to use, that I need to go back to Win98 as it will only run on this o/s. Can anyone tell me how to reinstall Win98 instead of 2000 NTFS? By the way, small glitch, I need to be able to do this by tomorrow(15th August) and the floppy drive doesn’t work so won’t be able to use it! Does anyone out there have a fairly easy and fast solution to this, without me loosing any of the programs already installed i.e. no formatting hard disk solutions please.
Thanks loads
