OK, please, following you have an updated one step ahead question regarding my first question post on the title.
The question now is, how possibly get some info or tracing/debug on, which possible reason is leading to this error referring to SYSPREP.
In the net I found several posts for this, and the following link do have quite exact instructions what to look at and try, and I have also been following most of them, except maybe one-two, which I now will still follow on a next Upgrade trial in few hours.
Here you have a summary of the background info for this case:
- Windows 10 Anniversary Upgrade is stuck at ab. 32% done, in a minute after the second (despite named as FIRST_BOOT) restart at 30%, during the actual final update process phase, with blank grey display and power-on
after an emergency power-off in a quarter or so, the Upgrade trial will got reversed and following error splash window will pop-up:
We couldn't install Windows 10
We've set your PC back to the way it was just before you started installing Windows 10.
0xC1900101 - 0x30018
The installation failed in the FIRST_BOOT phase with an error during SYSPREP operation
the laptop is some 7yrs old with dual-core AMD 1.9GHz 32-bit, memory 3GB, and has been working great with Windows 10 Pro (updated from 8.1) since 9 months
- I know there is outdatings with e.g. display driver, now run with the basic MS one, and Wi-Fi driver etc., but several of the risky devices and also software have been disabled during the Upgrade trials
I hope someone could help me some step ahead on this.
