Boot device not found after ANY Windows Update - XPS 15 L521X

Hello all,

I have a problem where whenever I install a Windows update, after a reboot, the laptop goes to 'Checking Media [Fail]' and then it tells me no Boot Device Found. After a reboot I end up in Windows Recovery and the only solution to boot into Windows is to do go back to a system restore point from before the windows update.

This happened when I installed Windows updates the usual way, but also when I tried to manually install the latest windows update (2004) from Microsoft's website.

The only workaround for me right now is disabling Windows Updates, but I know that's not the 'healthy' way to use a laptop daily.
