Last time I did this with the same machine(dunno what the bloke does to it) I tried booting from the Windows CD I could find no option to format the damaged disk only to begin the install,I just stuck the buggah in my machine as a slave and formatted it using disk manager but when I stuck it back into his machine and booted from the same windows CD,it formatted the hard again again for some reason,I can of course do the same thing again,just thinking that int olden days all one needed to do was stick in a floppy with the the config sys command com and format command on it boot from that type format and bob was yer uncle,life was simpler then.
