[*] Save it to your USB flashdrive as fixlist.txt
Boot into Recovery Environment
Start FRST in a similar manner to when you ran a scan earlier, but this time when it opens …
[*] Press the Fix button once and wait.
[*] FRST will process fixlist.txt
[*] When finished, it will produce a log fixlog.txt on your USB flashdrive.
Exit out of Recovery Environment and post me the log please.
Try to boot Windows normally…
