I'd like to resurrect this topic, as I'm experiencing the same issue as the OP, and took the same steps in attempt to correct it. This issue is being experienced on an HP ProBook 450 G2, using the Platform Pack for Windows 7x64. The image deploys fine on a Dell 7010 [with the appropriate PlatformPack]. Hot fixes and SmartDeploy storage patch for Windows 7 applied. Thoughts?
