Creators Update, 1703, upgrade fails with error 0x80070490 on Surface - Microsoft Community

i have been trying install creators update on surface pro 4 weekend without success.

first tried using windows update, downloaded iso msdn , tried using one.

the machine surface pro 4 running windows 10 enterprise , have 260gb free diskspace.

i don't have odd installed think on machine. i'm running hyper-v , visual studio main tools office 2016.

i have tried upgrade both connected surface dock , wihtout connected devices @ all... same behavior.

the upgrade fails @ same point in time, @ 29% setup aborts , operating system rolled previous version.

when using iso perform upgrade i following error message (sorry if translation swedish in error message wrong). 0x80070490, installation failed in phase safe_os error when performing prepare_first_boot.

i have tried several tips , trick found on internet solve error code. none have worked far.

tested among other things run "dism.exe /online /cleanup-image /restorehealth" make sure didn't have corrupt files.

two questions.

1. can find detailed logfiles showing details around error message?
