stuck at "working on updates" at 27%, reboots to rotating dots

HI all, this is the second of two laptops that I can't upgrade to Windows 10.

This is a Toshiba Satellite L665-S5156 running OEM installed Windows 7 Home, fully updated and activated with OEM marker present in firmware as per ShowKeyPlus. I am trying to upgrade this to Windows 10 Home using MediaCreationTool1909 from Administrator account, ethernet network hooked into working Internet connection.

Every time, it allows me a straight path to upgrade to Windows 10 Home, allowing me to keep settings, apps and personal data, progresses just fine to "Working on updates 27%", and after letting it run for about an hour with some disk activity, it reboots on its own, and ends up with the spinning dots and nothing else on the screen and no further disk activity. I let this be for up to 5 hours and no progress. I had to hold the power button 4 seconds to power cycle and it rebooted back into the same freeze. 3 times and then it did "Undoing changes made to your computer" (praise be) and I got back my fully working Windows 7 Home computer (with a "Setup is preparing your computer for first use".. ???) after another huge wait.

Once it reboots and I log back into the Administrator account I get a big window saying "We couldn't install Windows 10, We set your PC back to the way it was right before you started installing Windows 10" and the error: "0xC1900101 - 0x30017 The installation failed in the FIRST_BOOT phase with an error during BOOT operation". Going to https://support.microsoft.com/en-us/...llation-errors doesn't show this particular error.

I uninstalled as many 3rd party drivers as I could but there are still Atheros, touchpad and Intel drivers which I can't believe would cause this problem; in any case, uninstalling these would make my system unusable. I am in as clean a boot as possible. I have tried this with and without Avast anti-virus installed and as little starting up or running as possible. No joy.

The setuperr.log is huge (181K !!) with multiple errors. I can post the entire file here, but didn't want to and spam the forum. SetupDiag is no help: it shows only the same 0xC1900101-0x30017 error which appears to be a Rollback error? I can't find documentation for this error anywhere.

Any help would be appreciated; I am totally stuck here.

Thanks in advance.

How are you updating the best method if from media creation tool page hit update and let it do its thing. Is there anything in your paritions that would give the problem is there room for it to create recovery

The reported error code was 0xC1900101-0x30017
