Main steps for loading PE files into memory

1 when the PE file is executed, the PE loader first checks the PE header offset in the DOS MZ header. If found, ignore the DOS stub section and jump directly to the PE header. The 2 PE loader checks to see if the PE header is valid and jumps to the end of the PE header.

The 3 PE Loader reads the information in the section table and then maps the sections to memory using the memory file mapping method, and sets the properties of the memory block according to the properties of the Section table. After the 4 PE file is mapped to memory, the PE loader handles logical portions of the PE file similar to import table.
