Could it be a SATA drive that Windows doesn't have the drivers for?  That would create the case where edubuntu can see the drive but XP can't. Have you installed XP on this machine before? -Bryan <div> On 2/26/07, Simon Ruiz <<a href="mailto:sruiz@mccsc.edu">sruiz@mccsc.edu</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> You could probably boot to the Live CD, run "sudo gparted" from the commandline to bring up the partition editor and delete all the partitions. Or perhaps you could "dd if=/dev/null of=/dev/hda" to zero out the entire hard disk. *shrug* However, if Windows can't see a hard disk right now, I'm not sure what would make it do so, if you're certain the hard disk is plugged into the primary master position.
