Step 2: After decompressing the simulated virtual floppy drive.rar, run Vfloppy.exe and install the "simulated virtual floppy drive" to the D:\\BOOT directory.
Step 3: Use After WinRAR decompresses LOADISO.rar, it gets the file LOADISO.exe, and then decompresses LOADISO.exe with WinRAR to get LOADISO.IMA (don't worry about the error).
Step 4: LOADISO.IMA compressed dudu.zip, covering the D: \\ BOOT directory under the same name, this virtual drive using DOS boot disk when the system starts to boot up can be. Note: If a software like OneKey Recovery is installed on your system, it may not be able to boot properly.
