Thank you, pcuser, for making me look at the boot.ini file, and thank you Mike, for confirming what I found in the wee hours this morning.
The old hard drive has a hidden 55 meg FAT partition (EISA configuration) which is for diagnostics (or so I have read). The OS partition was #2.
So I have learned 2 things from this situation - always check the boot.ini file when cloning a drive and that Dell uses a strange drive configuration (and I read that others do as well).
Thank you to everyone that had an input - I appreciate all of the interest and assistance!
