Laptop can't start lhan2004-09-04 20:08:48

The SONY Laptop can't start. It gives
"Non-System disk or disk error
Replace and press anykey when ready".

After putting Win2K, WMe, XP reinstallation CD, It gives me
"Press any key to boot from CD.....
Non-System disk or disk error
Replace and press anykey when ready".

I insert a Win95 startup floppy Disk and it gives me the same errror.

Any suggestions?

Thanks!
