When reading the instructions on the IDE hard drive I learned that the black connector on the IDE cable is Master and the gray one is Slave with the drives set to Cable Select. I had to connect the drive I wanted to boot from to the black (Master) connector so I first booted from my DVD drive to boot from my Windows 7 disk so as to run the Repair feature which enabled the IDE hard drive onto the boot menu which was what I have been trying to accomplish. And then I switched the two drives and booted from my IDE hard drive.
Then I partitioned that drive and restored my Backup to the partition. This time it ran without problems so enabling the 8dot3 was the fix I needed so I thank you, Jim, for that clue.
Next I have to copy from the restored backup to the SATA drive that I changed from 32-bit to 64-bit.
After that (on the IDE hard drive) I plan to clear the new partition and expand the old one.
All of that should complete the work on the old PC that I am giving to my niece and her to boys unless I find something to add to it from the two older PC's she gave me to work on.
Then I can finally start working on the Dell XPS 8700 that I bought some months ago.
Plus I have the two laptops and tablets they want me to fix.
I'm sure your niece will appreciate the computer.
