AIO Boot supports multiple Windows installers in one USB/HDD. This article will help you choose one of two methods that are more suitable for you.
How does it work?
An ISO file of the Windows installer will contain the necessary files for the installation. Include bootloader files, menus, WinPE and Windows version images. AIO Boot already includes Windows bootloader files and menus. Here we only need two important files in the ISO file.
This is a WinPE, a small operating system that includes the installer and tools for installing Windows. First we will boot into this small operating system then the installer will start.
The installer will look for images of Windows editions, which by default are in source\install.wim or source\install.esd.
AIO Boot will modify the boot.wim file to interfere with its working steps. Or we will direct the path of the install.wim file. Or mount the Windows ISO file and let the installer work its way.
Advantages and disadvantages
Here are the advantages and disadvantages of two methods using ISO and extract install.wim.
- The size of install.wim is smaller than the ISO file, so it will save your disk space.
- You can save the install.wim file on the FAT32 partition if its size is less than 4GB regardless of its ISO size.
- No Repair your computer option. Perhaps this is the only reason I think we should use ISO instead of install.wim.
If you want to use the Repair your computer option and want to save disk space, repack the ISO file. However, this will take more time to process. Enable this option in Settings.
By default, the AIO Boot will use the Windows ISO file instead of the install.wim file. To switch to using the install.wim file, run AIOCreator.exe > Settings, select “Extract WIM for Windows Setup.” and Save.
