That stinks.. did you do an update or clean install??
Upgraded from build 10125 which initially stalled loading at 43%. Rebooted and the upgrade to 10130 continued normally but took about 45 minutes on this HP quad core (originally Vista) machine. Just made the ISO and burned it which will be used for a clean install on another desktop. Just wish for more improvements in Edge/Spartan and Cortana.
Tried three times, keep getting this error.
fbl_impressive Professional 10130 - Error 0x80200056
Did a search, but instructions a bit complicated for me.
Anyways, I'm upgraded to 10130. Mine worked from a leaked build as well. I install 10125 about 2 days ago. I ran windows update manually and it took the update and installed it just fine. Took longer because of the virtual machine, about 1 1/2 hours but I'm good to go now.
