Both my Alienware Aurora R5 desktop and Alienware R3 laptop got stuck on an infinite "preparing to repair" flash page upon restart and kept looping back to the page on both systems. I researched for days trying to bypass this garbage and ended up having to reinstall Windows 10 on both machines loosing everything.
I really am disappointed such a meaningless update bricked both systems as the update was clearly not ready. This really needs to be addressed for future updates. I will avoid any dell related updates like the plague in the future. I would not update this dell support update until this has been resolved.
