In Windows9x:

C:\>XCOPY *.* D: /C /H /E /K /R
SYS C: D:

will copy your drive and make it bootable.

Hmmm... shows how little I know...

But are we talking bootable, as in Windows 98 will run? In other words, if I were to FDISK my D: drive, then:

C:\>XCOPY *.* D: /C /H /E /K /R

could I then go to my BIOS, change the boot sequence so D: was the first boot drive (or alternatively, open the case and swap the cables and jumpers on the two drives), and my system would come up and run, just as though I were using the C: drive?

If so, this is exactly what I am looking for.
