I have a laptop IBM thinkpad celeron which was still working last week. But when I went to it today. it displayed "operating system not found". my problem is, the laptop doesn't have a floppy drive, or even a cd-rom cause it just have usb slot and external floppy. how can i fix it. thanks for your help!

Does the system "touch" the floppy drive if connected during a boot? (ie; does the drive light blink ON for a moment.)

If there is no way to control the system on bootup, the hard disk can be removed and with a 2-1/2" to 3-1/2" data cable adapter (couple of dollars) connected to a desktop system for drive analysis/corrections.
