sorry if this somehow ends up on the list twice....  I messed up sending....


I have dual boot Redhat and XP, boot loader is Grub, default is RH.  I 
am getting rid of the dual boot scenario and will have separate machines 
for both.  I have copied everything over to another machine on my 
network that I need to copy back to both OS' when I am ready.  What is 
the most efficient way of  wiping out both OS on my single disk?  
Unfortunately, all I really know is how to wipe out Windows with a boot 
disk on a Windows-only machine.  Since RH is the default and Grub is the 
boot loader, how would I proceed to clean up this machine?  Is there a 
command?  A disk scenario?
