I haven't had any of those type of issues on my PCs from Windows Update. Maybe download CrystalDiskInfo and see if your drive is reporting any errors.
I've had zero issues with any of the updates on any of my Win 10 systems. Can you give us the full text on the stop error?
disk and memory tests methinks.
memtest86 7.4 is my current preference assuming your system is UEFI capable. Having said this, when I first read your responses I thought you were referring to two different update scenarios but apparently just one. It wouldn't hurt to do a memory test though.
I'd start with checking the SMART stats as someone else suggested. If you can connect the disk to another machine you can read off the event logs on that machine and see whether it has been complaining about anything in particular lately. Running chkdsk /f /v /r on the M2 drive's file systems seems like a good plan.
If you can't boot Windows at present (I don't know if you know how to make this problem go away albeit temporarily), I'd boot from Win10 setup media and tell it to do startup repairs and the chkdsks from there.
I've had 50/50 luck with bootrec, I wouldn't rule it out. I once wasted a lot of time by not verifying whether the OS expectation for UEFI and the BIOS settings were in alignment though because bootrec doesn't tell you if you're wasting your time because the settings don't match up.
Everything is tied to the registry.
Has the system being playing up at all leading up to this?
Nope zero issues and that's what's frustrating and confusing. In both cases I delayed the update installs until finally they trigger on their own. It's the same system with no changes where I've run into this non booting issue after and update.
Had a case like this, brand new 1709 install about a month ago and the past three weeks it would bluescreen on boot and was fixed with bootrec but we needed a permanent solution. The last time I went out to remedy it, I used the dism /revertpendingactions command instead and it took care of it (see 'questionsformicrosoftproducts' post here for more). Survived this week so we'll see how it goes..
Exactly what version number do you have and what version number are you trying to install? There are some versions that will not update to the Creators update 16299. 0000. Is your current OS on the same m2 drive?
Honestly I don't know which version.
Click on Start then Setting then System, then About, scroll a little down and then "Wow a Miracle" 😵, you would the current Version and Last Update (OS Build).
Many times a working solution is to downland Update file from Microsoft and run it as is - https://www.catalog.update.microsoft.com/Search.aspx?q=windows 10 1709 x64
