hi, i think the problem most likely is that you just need to use the keyboad to navigate through the options. because the drivers for the mouse may not have been loaded by this point. if you cant reformat the drive using the CD at all then, try using FDISK. you can find information on FDISK here: http://support.microsoft.com/default.aspx?...b;en-us;Q255867 if you dont have a bootable floppy with the FDISK utitly on it, you can download one from here: http://www.bootdisk.com/bootdisk.htm hope this helps
