This is a historical Windows 10 media-recreation outcome. Preserve the intended installation target and its data; 0x8007025D alone does not prove faulty USB media.

  • A clean installation repeatedly failed while copying/expanding files with 0x8007025D.
  1. Re-created the Windows 10 USB installer on another computer and retried the clean installation.

Reported outcome: A participant with the same error confirmed the newly created media completed installation.

Use official media for the intended supported Windows release and a positively identified, backed-up USB drive. If fresh media produces the same failure, investigate memory/storage and the specific Setup logs rather than repeatedly reinstalling.
