Hi! Thanks for your help. To be honest, since I just click on ''unpdate'' in the windows unpdate panel of the setting app, I don't really know what my computer was trying to do or where to boot from, I just assumed it would have deal with the update itself. But your are right, I have managed my way out of this problem with the help of Dell Support. Thanks again!
I was trying to install the latest windows update (I don't remember the name of the update, but it's the latest one as of January 10th) and while doing it, my computer got stuck on the HTTP(s) Boot screen (see picture) It's been like this for about an hour. What should I do now? I don't want to mess up the update.   Thanks! [IMAGE]
