Create WINPE x64 Bootable USB with Acronis True Image 2015

I couldn't really find a definitive guide so this is how I got it to work using documentation from everywhere..please correct wherever I am wrong I will be happy to modify this.

***note I did this on a Windows 7 64 bit Pro installation

The official documentation only has x86 instructions which would be fine if the winpe files that you get from 2015 are 64 bit only...arrrghh...

Pre-Requisites

1. Windows AIK from Microsoft
2. Registered Acronis True Image 2015
3. Acronis Universal Restore Free Plugin from Acronis
4. Latest drivers from a place like DriverPack.net (torrent only unfortunately) or your own set of drivers.
5. Rufus (freeware) (for creating bootable usb)

Procedure

1. Assuming everything is downloaded and/or installed
2. Launch Deployment tools command prompt (DTCP)
3. copype amd64 c:\winpe_x64
4. create folder called mount in the winpe_x64 folder
5. Back to DTCP
6. imagex /mountrw winpe.wim 1 mount
7. Depending on where you put the drivers...do for all..driverpacks from driverpack have inf files in a directory a few levels down
8. Dism /Image:mount /Add-Driver /Driver:<> /Recurse /ForceUnsigned
9. imagex /unmount /commit mount
10. Now make a copy of this to use for whatever else you need a pristine WINPE environment to work with
11. Launch Rescue Media Builder
12. Select WINPE option
13. Select WIM file and save it somewhere easy to type in a command prompt ex. C:\AcronisMedia.wim
14. Back to DTCP
15. copy c:\AcronisMedia.wim c:\winpe_x64\ISO\sources\boot.wim

Here is where I get messed up and any help would be appreciated but it works so.....

16. For some reason the drivers you installed in steps 5-9 don't work with the acronis wim so you have to add them again....
17. create folder called mount in the C:\winpe_x64\ISO\sources folder
18. Back to DTCP
19. Change directory to C:\winpe_x64\ISO\sources
20. imagex /mountrw boot.wim 1 mount
21. Depending on where you put the drivers...do for all..driverpacks from driverpack have inf files in a directory a few levels down
22. Dism /Image:mount /Add-Driver /Driver:<> /Recurse /ForceUnsigned
23. imagex /unmount /commit mount
24. go back to the root of winpe_x64 in DTCP
25. create iso
26. oscdimg -n –bc:\winpe_x64\efisys.bin c:\winpe_x64\ISO c:\winpe_x64\winpe_x64.iso (manually type this...copy and paste doesn't seem to work to well)
27. insert usb key
28. open rufus
29. Make sure your USB key is selected
30. Click the cd icon next to "create a bootable disk using" and find the winpe_x64.iso that you created.
31. Make sure Quick Format and create extended label and icon files is selected too.
32. Start

Hopefully acronis can update their documentation with a 64 bit version but in the meantime this is a pain in the... but it works.

thanks
