My Latitude E4300 laptop worked flawless until the KB4100403 was due
for installation. The installation was performed and a reboot was
forced. When booting, the laptop shows a litte blue circle, which can
be moved with the mouse. This condition lasts forever. The windows-10
functional update 1803 is installed since May 2nd.

Any hints?

Start the computer, wait ten or fifteen seconds, then press and hold the
power button until the computer shuts down.Â* Do this twice and the third
time the computer should boot into the recovery environment.

Hi Ben
I made this several times. The only useable solution in recovery mode is
to restore the laptop using a system image. After that, the circle
starts again.
