How do you make bootable floppy disc of window NT?

From which platform? From a Windows platform, insert the floppy into your disk drive. You can do this any number of ways but I'll give you the two easiest for me: 1. Right click on start, hit explore, drag your data to the disk drive. It will copy it, not move it. Remove disk. 2. In the program that opens the data you want to transfer (so perhaps Word for a paper you wrote), have the data open in the window, click on File, Save As, and Save it to your floppy drive (usually drive A). Close program. Remove disk.
