OK. I realize now that I failed to give you enough info for anyone to offer an informed response.

Both OS's were bootable after Ubuntu installation, but Ubuntu wasn't acting right. That's another thread.

Thanks to everyone for your efforts. I think what made things most difficult for me is that there seems to be no definitive source to go to on this topic. I followed many threads on this and other forums and finally decided to just try something.

I deleted Ubuntu's partitions and the computer went into a coma. I then figured out how to repair Windows' bootloader and things seem to return to their original state.

Thank you again.
