A repair installation attempts to fix a damaged Windows installation while preserving existing data and settings, which is the opposite of what the user wants.

A multiboot installation keeps the existing Windows XP installation alongside Windows 7, allowing the user to choose at startup - this preserves the old OS and data rather than replacing them.

A clean install formats the target partition and installs the new operating system from scratch, ensuring no leftover files, settings, or potential compatibility issues from Windows XP carry forward. Because the user stated she does not wish to keep any data, there is no reason to attempt an upgrade path, which would also be unsupported directly from XP to 7. A clean install also produces a more stable and performant result than an in-place upgrade.

An upgrade installation migrates settings, files, and applications from the old OS to the new one; a direct upgrade path from Windows XP to Windows 7 is not supported by Microsoft.
