Every reboot I get error 0 x 000 21a the only way I can seem to get rid of this error is to boot into Falcon rescue Windows XP and use XP check disk which finds a bunch a bunch of reparse attribute errors, after fixing them it will reboot . Regular check disk from the wndows 10 CD does not fix it, neither do system restore, startup repair or any other windows 10 tools. I was stupid enough to trust Microsoft and that they did a good job and deleted the 35 gigabyte windows.old dir so prev. Build is no joy. I would prefer to fix vs reset/re-inst, PS fast boot, ide, safe bios defaults etc no joy..
