I think what the main problem is Reagentc.exe isn't updating the BCD store. After I run it, when I execute BCDEdit /ENUM ALL, I see everything is still pointing to WinRE on the OS's partition in the \Recovery\{GUID} directory. The way I run Reagentc is after 7 is installed, I hit F8, boot into Recovery, pick the command prompt and run the command. Maybe I shouldn't be running it from there. I'm trying something new. In WSIM (Windows System Image Manager), in the answer file, I created a Synchronous RunCommand during the OOBE phase, after first login. I have a cmd script that copies install.wim, WinRE.wim and boot.sdi to the recovery partition and then run the ReAgentc command. Perhaps this will work. If I can just get WinRE setup on the Recovery partition and have it recognize install.wim, I'll call this done. It'd be nice if this new way I'm trying it works. Then I can just deploy the images and it'll automatically set everything up and save me some time in the future.
