Hello All IT experts,

I have two operating systems in my laptop. one is MS XP and another is Windows Server. Since last one month server side is not booting at all. I was watching Youtube video and main Volume function didn't work. I tried to fix that but didn't work. So I restarted laptop but the server side did not boot at all no matter how log I wait. So I switched to XP side which has around 6 GB space only. Since then I have been working on XP side only. If there is any way to fix that problem (rebooting the Server side) that will be great.
If not, I want to reformat and want to have only one operating system but I don't have any OS disc with me.

What will be the best option and way to fix this proble?
Thanks in advance for your valuable suggestion.
