My experience has even been that you have to format the disk prior to
install dos 4.x. I tried to make the disk bootable with Norton Disk
doctor. It resulted in a desaster: After 2 days work with Dos 4 suddenly
partition table, boot sector, FAT and root directory on the first
partition became overwritten by a file that I wanted to write to
the second partition.

I continue using Dos 3.3.

Does anybody know a way to uprade DOS without loosing all data ?
