I had tried from the early win10 early betas to upgrade from win 8.1 pro 64 bit. I continually got
the error: "The installation failed in the SECOND_BOOT phase with an error during MIGRATE_DATA operation" and the code "Error 0x8007002C - 0x4000D". I had tried the fixes recommending by microsoft, including disabling/unistalling antivirus(Bitdefender), removing unneeded peripherals, scanning system files, to no avail. After months of trying various builds, including the final, no luck. I had tried upgrading via iso and windows update. Every time the installation hung at the same spot 86 percent. However, I was finally able to get build 1511 11082 to install. Now, however, my concern is the expiration date in July 2016. I have tried unsuccesfuly via windows update and iso files to upgrade to newer release preview versions, however the error message returns(installation hangs at 86 percent) and the system rolls back to my current version of win 10. Any help or suggestion would be appreciated. Homebuilt PC, fx6850 cpu, asus m5a99fx board. I am able to clean install with no problems.
