If I recall correctly, you should be able to install an x64 image from x86 WinPE, dism /apply-image, /add-package, and /apply-unattend should be bitwise agnostic.
Is there a specific problem you are seeing?

You can do it before the OS is applied on HP devices, but we had to move it to the middle of the process for Dell machines. (We moved to 64-bit media a couple of years ago to support UEFI and Windows 8.)

On Fri, May 8, 2015 at 10:29 PM, Miller, Todd <[email protected] <mailto:[email protected]> > wrote: I used to use 32bit WinPE to deploy both 64bit and 32bit OSes. But something happened a few months back where I had to switch so that the bitness of WinPE matched the OS being deployed. I think it was caused by driver injection problems, but I can’t remember exactly. I feel like I read the advice on DeploymentResearch.com, but I can’t find the post now. Anyway, matching the bitness fixed my problem. Now I am in a little trouble with this because I would like to update the BIOS on Dell computers during OS Deployment and it looks like Dell only has 32 bit versions of the BIOS updates available. I think I cannot run a 32bit executable to update BIOS while I am booted into a 64bit WinPE version. I could briefly boot into a 32bit WinPE boot disk while updating the BIOS and then continue on in WinPE 64bit, but the only two options for rebooting are into the Full OS or into the WinPE boot disk assigned to the Task Sequence. Is there a way for me to reboot into a specified WinPE image, update the BIOS, and then reboot back into the WinPE that is assigned to the task sequence? Is there a way out of this problem? One thing I can think of would be to do the BIOS update as a prehook before the real Task Sequence starts… _____ Notice: This UI Health Care e-mail (including attachments) is covered by the Electronic Communications Privacy Act, 18 U.S.C. 2510-2521, is confidential and may be legally privileged.
