[newbie] Making Copies...Help!!

[Anonymous]

Does anyone know how to create a linux boot disk...I want to make copies of
the boot disk that came with Mandrake but when I do under windows it will
not work.  The files seem to copy fine but the disk will not work as a boot
disk.  Also how do I burn copies of the CD's?  I know they say make all
files exe but how do I do this under Win98??  It does not give me an option
under properties to make files exe...
