Glad you found a workaround. It's interesting that i have to disable Fast Startup for a completely different bug. With it enabled, I can't do a GUI shutdown (Start\Power\Shut down, or Sign Out\Power\Shut down). My screen blinks and then sends me right back to the desktop again. Disabling Fast Startup solves that one too.
I already have SSD hard drives only.
I have just found some helpful information about this on the web.
In part, it says:
"If you already installed build 17101 on your computer and experienced boot loop issues, you’re not the only one."
"Fortunately, we also have a piece of good news: you can quickly fix this problem by unchecking Fast Startup in Power Options."
I'm right now in the process of seeing if this solution works.
Most of the install seems to happen right after the download has finished
Takes about 45min of doing stuff in bacckground, i was happily playing away, with occasional stutter
Then wants to reboot, within seconds at 30% reboots again, then seems to sit in the 80's for a while, before final reboot
I much prefer this install
As for not booting up on your machine, you need to get your self a SSD, you won't know your self with boot time (or not in your case)
Never going back to HDD boot again
On my HP which had a really fast BIOS boot phase, I was up and running in <10secs from a shutdown, my Dell takes about 15secs as BIOS does a bit of mucking about.
