Creating a Windows 7 "All-in-One" (AIO) installer allows you to choose between various versions (Starter, Home Basic, Home Premium, Professional, and Ultimate) during a single installation process. Basic Method: Deleting ei.cfg
Restart your PC and enter BIOS (Usually F2, DEL, or F12).

Versatility: Includes both 32-bit (x86) and 64-bit (x64) architectures.
