I have windows XP and on boot up at the "Welcome to Windows stage, I get the message "WINDOWS NO-DISK" then in text THERE IS NO DISK IN THE DRIVE. PLEASE INSERT A DISC INTO DRIVE. with the options CANCEL, TRY AGAIN & CONTINUE. If i click either continue or cancel 45 to 50 times it continues the boot up. I have reinstalled windows with no luck and found that if i go into MSCONFIG and uncheck PLUG & PLAY in the services it fixes it, however I can't then connect to my wireless modem to go on line.
Please, anyone, it's killing me here! thanks
