Hi tried the safe mode as well and it is not recognising there too.
It is showing ''DISK is not formatted'' as a header. and under it '' windows cannot read this disk. The disk might be corupted or it could be using a format that is not compatible with windows'' was showed along with 'close' tab.
And when I tried to open the control panel in normal mode, it showed up like earlier, but when I asked it to send error report, it is recommending to update it to XP-SP2.
I tried to upload the page shown, but its not allowing to upload .doc file...
