I take it this laptop computer cannot be configured to boot to CD. Is that correct?
Many of the older models that would not allow that, but came with interchangeable drives also came with a cable that you could connect between the floppy drive and the laptop, thus allowing you to have the CD in the bay and boot to the floppy.
Just thinking out loud here...........
If not you will need to use the floppy drive to format the hard drive, install dos, find the appropriate CD drivers, load them on the hard drive, edit the autoexec.bat and config.sys (the specs should be included with the dos drivers). Problem here is Windows 2000 wants to install to FAT32 or NTFS formatted partitions.
