Anyone have any luck fixing this? The installation failed in the SAFE_OS phase error during Replicate_OC operation.

Windows 7 home to windows 10 home upgrade.
Customer has many programs and setting they must keep.
 
Something mucked up, IIRC, it usually has a lot to do with the BS factory partitions from Dell, HP, etc.

Must copy the system partition, format the drive and restore only the Windows MSR and System parts.
 
Were you doing it from an ISO extracted directly to the C drive? Did you uninstall all AV before proceeding?

Install was 1909 from cd uninstalled all AV and all drivers the system is an A4 on a gigabyte board with 8gb ram newest bios.
also did chkdsk and sfc and disk cleanup no issues. nothing running in the background other than windows services that is needed.
 
Hopefully you have an image which you can put on another drive and try it again. Not common but it's happened enough to remember that the patient drive has bad sectors somewhere that never get touched during normal operation but get touched during something like an upgrade or large app install.

did i say somewhere there were bad sectors did full surface test with chkdsk no errors or issues.
Odd thing i have had this issue with same systems same board same cpu and operating system did the same thing uninstalled all drivers and av and did full hdd surface test and ram test no showed no problems.

The hard drive also has 450gb of free space and yes i image the drive before doing any upgrades of OS..
From what i have found on google is that some windows update is responsible for windows 7 upgrade to windows 10 Issues what update i am not sure although i could do an in place windows repair would wipe out all of those updates.

Yes, I saw what you had already done. Doesn't change my comment. Our world is full of false positives and negatives from "tests". I long ago stopped relying on those and instead look at what is actually going on. Which is why, many times, I'll just move to another drive.

I found the problematic update i removed kb4530734 and the upgrade has gone though without any issues doing a windows 7 upgrade repair.

As far as drive test smart test do seem unreliable at times but surface tests using good software is 100% reliable it takes a good 2-4 hours like hddscan.
