I hope all goes well for you at the hospital, Pete.
How did you get on with the Startup Repair before, or didn't you try it ?
If you haven't, then run that up to three times if it reports it is unable to auto repair.
Also, at the cmd prompt see what chkdsk c: /f reports and make a note if it reports any KBs in bad sectors.
I don't understand why things should have gotten worse after running those Bootrec cmds - after each cmd, was there any message ?
Depending upon what the chkdsk reports, as your wife has a working machine, you could create a Paragon Rescue Disk and boot up with that.

You can leave these until Friday if you like and just let me know then how things turned out.
