Hi people, first post here! I would prefer to post good news but I'm having trouble updating to Windows 10, so I need you help. I've tried with the windows update application, but also with a downloaded iso without luck. The thing is that when it is in the process of copying files, around 25% of the total (~60% of copy files phase) it reboots and then rolls back to win8.1. I'm desperate, I've tried disconnecting every peripheral (even the kb and mouse) and hard drive and also disabling a lot of startup stuff and windows defender etc. but always get the same result. Drivers are up to date and I have more than 30gb of free disk space. My system is Windows 8.1 Pro on a Samsung 840 evo 120gb ssd with 8gb of ram and an AMD FX 8320. The error I get get it boots back to 8.1 is: 0x80070002 - 0x2000A: Installation error in SAFE_OS phase with an error during the PREPARE_FIRST_BOOT operation. Is there a log I can take a look at?
