I have a colleague who upgraded a Win98 machine to WInXP. The install didn't go to plan, now nothing works. I gave him a Win98 boot disk so he could format his drive and start again but he is having problems formatting his drive. When he attempts to do this, it says 'Unable to format c:, drive unrecognisable'. He tells me he created a virtual C:\ drive but didn't label it. I have attempted to talk him through FDISK but he says he is uanble to delete any aprtition. Can anyone point me in the right direction please. Lamaar75@hotmail.com
