I have found instructions to remove Watchdog, but all I've seen so far require that the system be running. Mine refuses to go beyond the "Phase 0; Phase1" displays, after which it essentially freezes, or more probably loops somehow, as it does continue to show disk action periodically. When I first got the (refurb) system it was already doing this, but would go on to let Windows load after a few reboots. At that time the system was on W7; I upgraded to 10, and hoped that would fix it, because I hadn't a clue what "Watchdog" was and thought the new OS would likely get rid of it; It obviously didn't, and then it stopped progressing to load Windows no matter how many reboots I tried. I didn't realize it was malware until a few days ago (doh!). Note: I can interrupt the boot with "setup", but can't figure out how to change anything relevant from there.
