*Note, this is not running DD or TI from within BartPE but as an option to load DD or TI at boot time.
*My method requires Grub4Dos. I'm not a BCDW user but I'm sure someone can make it work with it.
First, you need the plugin I created here at: Multiboot CD with Grub4Dos.
Once you create the plugin, then all you need to do is add some files to your Boot folder ([Plugin Folder]\[Multiboot Plugin Folder]\Boot\) and modify your menu.lst.
1) Collect files
1a) If you want to add True Image, create an ISO of True Image and copy all the files in the "Recovery Manager" folder to [Plugin Folder]\[Multiboot Plugin Folder]\Boot\Acronis\TI. The files will be of the sort: bootmenu.exe, bootwiz.sys, f11.cfg, kernel.dat, mouse.com, ramdisk.dat, and splash.run. That's a total of 7 files.
1b) If you want to add Disk Director, the process a bit different since an ISO has no files. You'll have to create a bootable USB with DD. So create that first. Then, copy the files from the USB to [Plugin Folder]\[Multiboot Plugin Folder]\Boot\Acronis\DD. There are 14 files. Some of them are dat2.dat and dat3.dat.
As long as you create a folder within the Boot folder, then all your files should copy without having to modify the inf file.
2) Add entries to menu.lst. The following two entries will load the two apps, respectively.
CODE
title Acronis Disk Director (Enter "product" at busybox prompt)
kernel /Acronis/DD/dat3.dat vga=791 ramdisk_size=32768 mbrcrcs=on
initrd /Acronis/DD/dat2.dat /s
title Acronis True Image (Enter "product" at busybox prompt)
kernel /Acronis/TI/kernel.dat vga=791 ramdisk_size=32768 mbrcrcs=on
initrd /Acronis/TI/ramdisk.dat /s
kernel /Acronis/DD/dat3.dat vga=791 ramdisk_size=32768 mbrcrcs=on
initrd /Acronis/DD/dat2.dat /s
title Acronis True Image (Enter "product" at busybox prompt)
kernel /Acronis/TI/kernel.dat vga=791 ramdisk_size=32768 mbrcrcs=on
initrd /Acronis/TI/ramdisk.dat /s
Note that you will have to type "product" at the busybox prompt to load either of these apps. So, when the booting stops, it will wait for you to do something.
