Replaced CLFS.sys with the latest version I found in WinSxS besides the one from the backup folder (I backed up the one that was in the drivers folder by renaming it to .bak. The replacement file was much larger +/-351kb vs 51kb). I had to do the same with cng.sys, as it was also corrupt. When I rebooted, the boot went further but eventually blue screened. So I attempted to use the files from the WinSxS\Backup folder instead, but then the original error saying the files were corrupt came back (the files in the backup folder were the same size as the original files).
