W10 1809 - Hyper-V doesn't work anymore after upgrade from 1803 (VT-d)
Hello,
unfortunately I decided to upgrade from Windows 10 1803 to 1809.
The upgrade did fail everytime. (Error-Code: 0xC1900101 – 0x40017)
After hours of troubleshooting, analysis of setupact.log and looking for answers on the web I did find the following solution: Link
It is german, but the user had the same problem and it was solved by disabling Hyper-V.
I did disable/uninstall the Hyper-V role/function and the upgrade to 1809 was finally successful.
I did not install Hyper-V just for fun in the past and I did try to enable it again in 1809. The activation of the role needs a reebot.
The reboot was NOT successful and Windows did NOT start anymore.
After doing research on a second computer I did stumble over problems regarding the "VT-d" technology:
- PSA: Disable VT-d in your BIOS if Windows 1803 fails to update and is stuck on the blue logo : windows
- Windows 10 1809 bereitet Probleme bei der Installation Tipps und Tricks Deskmodder Wiki
- Can't boot with Intel VT-D enabled, since build 17025
- …
I did disable VT-d in BIOS/UEFI and Windows 10 1809 did finally start.
Of course Hyper-V does NOT work without VT-d and now I am fu****
The BIOS/UEFI is on latest Version of the vendor.
I did install latest 1809 cumulative update from yesterday. I did try to disable some of the new security-function of the OS, but this did NOT help either.
My CPU is AMD X6 and AMD 870 chipset.
I did a roll-back to 1803, because I need Hyper-V.
What could I do to get this fixed?
What could I do to inform Microsoft about it more directly?
Thank you
