ok, a short background: I have WinPE working great. I am trying to install an unattended Win2k3 Server install. 1) I use diskpart to clean and partition the drive 2) Then use format to format to ntfs. 3) Then run the winnt32.exe with command line switches. Once it is done, it reboots to a black screen with a flashing cursor. Things I have tried (on PATA, SATA, SCSI, SAS): 1) running "bootsect /nt52 c: /force", right before the winnt32.exe setup is run 2) running "MbrFix /drive 0 fixmbr /yes", right before the winnt32.exe setup is run If I do the same steps on WinPE 2005 based on Win2k3SP1, it works fine. Any ideas? Am I missing something obvious?
