My system is Windows XP SP2. There is an xcopy file in c:\windows\system32. I copied it to the Win98 boot disk. After booting with the boot disk, the xcopy program cannot be run. The command I used is: xcopy c:\123\*.* g:\456/s. The returned message is "....is neither an internal or external command, nor a runnable program or batch file". What's the matter with this?
