I downloaded the ISO from MSDN and tried to update my Anniversary (1607, Enterprise 64-bit). After the initial reboot, it always says it failed because:
The installation failed in the SAFE_OS phase with an error during PREPARE_ROLLBACK operation.
I Googled all around and tried all solutions found but to no avail. I've even tried all solutions found for the same error code for Windows Update and Windows Store! Also all results that Google provided me with have an error code of
0x80070002-0x20009
but mine is 0x80070003-0x20009
.
Because I have heavily customized my system (nothing deep into, just bunches of links and themes that I'm extremely sure not to be the cause) so it's highly impractical to do a fresh install. Can anyone help? Thanks in advance.
Edit: Fixes I've tried by far:
- Create a temporary Adminsitrator account and try to update from that account
- Configure a clean boot in
msconfig.exe
(and in Safe Mode as well) DISM.exe /Online /Cleanup-Image /RestoreHealth
andsfc.exe /scannow
in an elevated Command Prompt (Both told me there's nothing wrong)- Remove a secondary HDD (Primary is an SSD)
- Get rid of extra EFI System Partitions and a secondary Windows 7 installation partition (and its BCD entry). Currently there's 4 partitions on my primary SSD:
1 ESP BOOT FAT32 400MB 2 PRI Windows NTFS 158GB 3 PRI Data NTFS 10GB # For personal files 4 PRI ubuntu ext4 64GB # 16.04.1 LTS, UEFI boot from #1 ESP
- Download some Windows Diagnostics packages from MSDN and diagnose with them
