Windows 10: Stuck in start up loop after Windows update

3 days ago I was prompted to do a Windows 10 update on my Dell Inspirion 15 5570, and now my laptop is stuck in this start up loop and will not boot to Windows, can someone please help me. Here's exactly what happens when I power it on:

1 It makes it past Dell logo.

2 The blue bar fills all the way.

3 Circle spins.

4 It quickly flashes 2 messages:

A- Attempting to recover installation.

B- Undoing changes made to your computer.

In my opinion it doesnt have time to do either because next, it shuts down and restarts, and this is what it does over and over, it wont go any further then this.

Ive read several times that if I cycle my laptop on and off 3 times, after the 3rd attempt to boot has failed, Windows 10 will automatically boot into Windows Recovery Enviroment, but mine does not mine goes to Support Assist and does a system scan, Ive allowed that scan to completely finish and no issues were detected with the laptop so it definately has something to do with that Windows 10 update. Because it goes to Support Assist after 3 boot attempts Im not even sure how to get to Windows Recovery Enviroment to try the steps I read about. Im even willing to do a factory reset to see if that helps, but I cant even figure out how to get to that. If anyone has any suggestions Id greatly appreciate it. Im not very good with.computers and computer language, so if you could explain your suggestions as if you were talking to a 7th grader it would help me tremendously. Thank you so much for taking the time to read about my dilemma and any advice you might have to offer.

Win10: windows update stuck at never ending loop ?

When in win10:

• Update&security -> Windows update -> Finding update... .... .... ....

Planning to download the latest Win10.ISO (vers.1803) and manually update:
- Then wait that my ordered new SSD arrives and clone the old HDD to it.

 

Stuck in update loop

These are the only three devices with warning triangles. The PS/2 keyboard and mouse were listed before. The JMB 36X is new.

 

Computer did automatic update and is now stuck in start up loop

I had no trouble updating to Windows 10, but this last automatic update has caused my computer to be stalled in Start up loop. I have tried the booting from the USB Repair step and when it restarted it did the same thing. Stuck in the Restart/Start up loop.
