    Hello and welcome to Windows Central.

    There's good news and potentially some bad news.

    The good news is that the issue you've described is known and is in fact described in our referenced article here: Here are the known issues in Windows 10 Mobile build 10586, and to quote

    After we released Build 10581 to Windows Insiders in the Fast ring, we discovered a bug in the build that will cause the filesystem to become partially corrupted after doing a factory reset. For those of you who did a factory reset of your phone, you most likely did not notice this issue on Build 10581. Due to this bug however, upgrading to Build 10586 will cause your phone to go into a reboot loop after the upgrade completes – rebooting at the Windows or operator logo. To recover your phone, you can use the hardware key combination to reset your phone which will then put it at the OOBE experience on Build 10586. We highly recommend that you make sure you do a backup your phone before upgrading to Build 10586 due to this bug. Additionally, you can also recover your phone by using the Windows Device Recovery Tool to go back to Windows Phone 8.1 and then upgrade to Build 10586.
    Notice, however, that the original article puts emphasis on backing up your phone "before" upgrading.

    The bad news is that you may lose all your data if you weren't able to back your phone up first.

    Despite that, you may create a Windows Central account to Reply in this thread for further correspondence.
