I have a Samsung laptop, RC512. Something happened to it and it will do almost nothing. It wont update at all. All the updates it has tried just fail. I really want to update it to windows 10 but it just fails. I've decided to factory reset it and I've tried everything and it wont! I tried using a repair disk and selecting System Restore but all the restore points don't go back far enough to help my pc. I've tried using the Samsung Recovery Solution 5 that my computer came with. Well its not even showing up when I press F4, turns out it got removed from my last factory reset that I did. So, I went to redownload the Samsung Recovery Solution 5 and..... It doesn't install. It says something about how "'u' is not a integer value." I have no idea what to do now someone please help me.
