Reserved upgrade from Windows 7. Clean PC with no issues completely updated. Instillation goes smooth until it gets to the part where it's copying files. Then gives the error 0x80070004 - 0x2000D The installation failed in the SAFE_OS phase with an error during MIGRATE_DATA. 186GB free on hard drive. Ran chkdsk/repaired sectors, did subinacl, defrag and sfc scan came back clean. Same error. Not sure what to do? Any help would be appreciated.
