Bootable Media Builder provides three methods of integrating Acronis Backup with WinPE:
Adding the Acronis Plug-in to the existing PE ISO. This comes in handy when you have to add the plug-in to the previously configured PE ISO that is already in use.
Creating the PE ISO with the plug-in from scratch.
Adding the Acronis Plug-in to a WIM file for any future purpose (manual ISO building, adding other tools to the image and so on).
Bootable Media Builder supports WinPE distributions that are based on any the following kernels:
Windows Vista (PE 2.0)
Windows Vista SP1 and Windows Server 2008 (PE 2.1)
Windows 7 (PE 3.0) with or without the supplement for Windows 7 SP1 (PE 3.1)
Windows 8 (PE 4.0)
Windows 8.1 (PE 5.0)
Bootable Media Builder supports both 32-bit and 64-bit WinPE distributions. The 32-bit WinPE distributions can also work on 64-bit hardware. However, you need a 64-bit distribution to boot a machine that uses Unified Extensible Firmware Interface (UEFI).
PE images based on WinPE 4 and later require approximately 1 GB of RAM to work.
