If you do not have USB or external CD-drive in bios boot options, you are not going to be able to boot to that drive.
You didn't mention the cd-drive model. A slim hope is thay have a DOS driver and your laptop supports legacy usb devices. I wouldn't not count on it.
What I would do in your case (assuming you lack an RIS server--him, that is redundant), is head to newegg or a local computer store, get yourself a 2.5 drive enclosure, put your notebook drive in there, copy the windowsme install files to a directory on the drive using a different computer, reinsert in laptop, install windowsme from the directory.
