Thanks for the advice. I found the problem. Somehow - who knows why - the first physical partition got changed into an extended partition. I guess that during the last OS install Windows saw that it couldn't make that the boot partition though it could put all the OS files there. It put the files boot.ini, ntdetect.com, etc., on the next physically available partition, though somehow it determined that it was partition #4, not #2.
I had to run System Commander off of its boot CD in order to convert the extended partition back to a "normal" (primary ?) one. This, however, wiped the partition of all data, and so, I had to do a re-install. I'm getting pretty good at doing re-installs, setting restores and application re-installs !
