dos 5.0, non-system disk error

Specs: DOS 5.0, X286
Hi,
I have two old x286 computers running dos 5.0 from 3.5" floppy drives. There are no hard drives in these computers. One of the computers took a dump, and using the floppy disk from the other computer, I have determined that the problem is disk failure. Using a new disk, I copied all the files, hidden/system and otherwise, over to the new 3.5" floppy from the working disk. When attempting to boot from the new disk I get a non-system disk error. The disk from the other machine works fine on this machine, so I know the machine works. With dos 5.0, can I just copy over the files, as long as I get them all?
Thanks.
Rick

You have to use diskcopy, to make a one by one copy of a bootable system disk.
E.g.:
If you only have one floppy disk drive, use this command:
diskcopy a: b:

Then you have to change disks several times until it has finished.

diskcopy didn't work, but I did get it to work. I used bootdisk.com.
Thanks.

Yeah, the hidden system files--io.sys and msdos.sys--can't just be copied anywhere on a disk. You have to use the SYS command or, as mentioned, DISKCOPY since it creates an exact duplicate of the disk.
