Sometime during the night Windows downloaded updates to my Dell desktop. Screen response: "updating stage 3 of 3 0% complete."
Then after awhile it restarted and went back to same screen. Appears to be in a loop. Tried System Restore, no restore point available.
Then attempted to load Windows install disk that came with system., It ran for awhile into about 27% installing, then the response::::: Installation cancelled
" Windows could not update computer's boot configuration. Installation cannot proceed."
