I am installing Win2k8 RC0 (Longhorn) from network attached WinPE2.0 or WinPE1.6. WinPE1.6 works without error, however WinPE2.0 has an issue. I am using the same set of scripts on both platforms, so I know I have the basic process working. After starting the Longhorn install from WinPE2, I get the following error message before the install fails: Error Window Title: "Install Windows" Error Window Text: "Windows Setup could not install one or more boot-critical drivers. To install Windows, make sure that the drivers are valid, and restart the installation." I've done searches for this error, and I can't find it anywhere. Anyone else seeing this now or in the past?
