Back up after computer hit by a surge and upgrading from XP to 10

I upgraded to 10 but need to retrieve my old "Documents and Settings" folder.  I can run the Recovery Point Browser from my backed up Program Files but the only option that I get is to recover it to C.  With the way 10 handles "Documents and Settings" folder making it inaccessible that doesn't help.  I tried using Falcon'sFour Boot disk running it as MiniXP and a bare partition hard drive with the first partition labeled as "C" and recovering it there.  I double click on the exe and get an error message that I need dbghelp.dll.  How do I fix this?
