Chkdsk did finish normally and continue to boot. I just ran SRC/scannow and it said, "Windows Resource Protection did not find any integrity violations." I copied the Desktop folder from C:/users/StupidPlant to the ...systemprofile\ folder, which eliminated the "\Desktop refers to a location..." error but did not resolve the issue with my inability to run commands from the "Search programs and files" field. I now get an I icon in the quick launch area saying, "You have been logged on with the default profile for the system, please see the event log or contact your administrator." Also, twice during my efforts over the last day to resolve this issue, when the system booted, it would come to a black screen with only the cursor visible. I tried ctrl+alt+delete, which did bring up the usual screen, but anything I did from there went back to a black screen.
