Windows 7

Hi all

ive been trying to format my toshiba laptop satellite pro a210 but wont let me format the C drive normal or in safe mode. Its orignally windows xp but i had windows 7 put on it. I have the xp cd but my cd drive doesnt work and tried it numerous of times.

I also tried it with a usb downloaded xp from microsoft and rebooted it with a usb. It says missing operating system.

I really need to format it to any windows xp or 7 and make it perfect again.

Can anyone help me.


Please

thank you
