I have a pc running windows 10 that goes to the recovery/repair window upon boot with the error " The operating system couldn't be loaded because a critical system driver is missing or corrupt" File: windows\system32\drivers\spaceport.sys. It will not let me choose any of the recovery tools It just goes back to the previous screen. I booted the pc with Windows 8.1 SE so I could replace the corrupt file. I have tried everything I can think of to delete the file but I keep getting the message "ERROR the file or directory is corrupted and unreadable. How can I get past this and force delete the file?
