Issue

Windows may report: 0xc000000e boot error (The boot selection failed because a required device is inaccessible) when a non-sysprepped base image is restored via the Zim development menu (WinPE imaging)

This issue occurs because the Boot Configuration Data (BCD) store cannot locate the Windows partition(s). A sysprepped image has a different BCD setting that allows the Boot Manager to locate the appropriate partitions.

Solution

Modify the zim.cfg file to update the BCD store after the image has been restored.

Requirements

• ENGL WinPE 5 imaging environment
  
  
• zim.cfg file
  
  
• Text editor
  
  

Procedures

1. Modify the zim.cfg file

   • Open tftp/zimfiles/zim.cfg file in text editor.
     
     
   • Update the section with the following lines (shown in green):
     
     

     Label:Dev_Restore_Image_Name
     
     ; Launch a Form to enter image name
     Form:Start,"Form_RestoreImageName","Enter image name","_OkCancel^_Ok",Blue
     Form:Item,"Item1",Label,"Image path"
     Form:Item,"Item2",EditBox,"%Restore_Image_Path%",ReadOnly
     Form:Item,"Item3",Label,"Enter image name"
     
     If:Var,Lookup_Image_Type,EQ,"Other"
       Form:Item,"Item4",Browse_File,"%WimPath%","Specify a WIM file","%Images_Path%","wim","open"
     Else:
       Form:Item,"Item4",EditBox,"%Image_Name%"
     End:
     
     Form:Display,"Form_RestoreImageName"
     
     If:Var,_Form,EQ,"_Cancel"
       Menu:Return
     End:
     
     Set:Image_Name,"%_Form_RestoreImageName_Item4%"
     Set:ExtensionCheck,Right("%Image_Name%",4)
     
     If:var,ExtensionCheck,NE,".wim"
       Set:Image_Name,"%Image_Name%.wim"
     End:
     
     File:Run,"net use "%Images_Path%" /user:%Images_Share_Username% %Images_Share_Password%",silent
     
     If:Var,Lookup_Image_Type,EQ,"OS"
       Wim:Apply,"%Images_Path%\%Restore_Image_Path%\%Image_Name%"
       If:EFI,Exist
         ; Copy boot files from the Windows partition to the System partition
         File:Run,"bcdboot %Project_Partition%\Windows"
     End:
     File:Ini,Get,"%_ZimDir%projects.ini","%Lookup_Project%","Base_Image",Base_Image
     
     If:Var,Image_Name,EQ,"%Base_Image%.wim"
       ; Image name matches project 'base image' name therefore we are restoring a sysprepped base image.
     else:
       ; non sysprepped image restored so we need to update the bcd store with the correct paths.
     
       If:Var,Partition_Count,EQ,"1"
         File:Run,"cmd /c bcdedit /set {default} device partition=C: >> %_ZimDir%/zim.log"
         File:Run,"cmd /c bcdedit /set {default} osdevice partition=C: >> %_ZimDir%/zim.log"
         File:Run,"cmd /c bcdedit /set {bootmgr} device partition=C: >> %_ZimDir%/zim.log"
       Else:
         File:Run,"cmd /c bcdedit /set {default} device partition=D: >> %_ZimDir%/zim.log"
         File:Run,"cmd /c bcdedit /set {default} osdevice partition=D: >> %_ZimDir%/zim.log"
         File:Run,"cmd /c bcdedit /set {bootmgr} device partition=C: >> %_ZimDir%/zim.log"
       End:
     End:
     
     ElseIf:Var,Lookup_Image_Type,EQ,"Other"
       Wim:Apply,"%Image_Name%"
     Else:
       Wim:Apply,"%Images_Path%\%Restore_Image_Path%\%Image_Name%","1","%Project_Partition%"
     End:
     
     File:Run,"net use "%Images_Path%" /delete /yes",silent
     
     Menu:Return

   • Save changes to the zim.cfg file 

2. Test updated files

   • PXE Boot a machine to the ENGL PE imaging environment. 
   • Select Maintenance Menu
   • Select Development Menu
   • Select Restore an image
   • Select Image Type : OS and select appropriate Project from the drop down list 
   • When prompted for the image name enter the appropriate file name 
   • Select OK. The image should now restore successfully 
   • The machine will now deploy successfully.
