hi guys i have a problem that occured from nowhere , im on my old computer now

i was on my other computer less than 1 hour ago so windows kept lagging and not responding.
done all my cleaners and still the same i done a scan disk check on the next boot up but it never got to that stage it just takes a long time to recodnize the keyboard and mouse then will go to windows is starting...the logo does not appear and thats as far as it will
go. have put the repair disk in its took a long time to recodnise it loaded for a while its still loading now , mite of stopped i aint sure , am able to access the bios

now on bootup it is only detecting the cd rom and mouse and keyboard

went into bios , it isnt showing sata hard disk for a first boot device ,

edit , got into the repair options but the disk did not pick up a window operating system !

Check the hard drive with the manufacturer's diagnostic tools.
