Question

Here is my scenario:

I have a server with 2 possible configurations: 2-TB HDD which require no special treatment or 3-TB HDD that require a UEFI BIOS and a GPT partition to boot the OS.

I am trying to create a single installation USB key that is able to detect whether the BIOS is ‘legacy’ or ‘UEFI’ and execute a deployment script accordingly.

I looked hard for a WMI that can make the distinction but to no avail.

The closest that I came to a solution is this post:

detectefi.exe works perfectly in detecting the BIOS type, but I can’t output its result so I don’t know how to use it.

I have 2 questions:

1. is there any WMI that I can use to distinguich between my 2 set-ups.

2. (if the answer for question 1 is no) is there a way to output the results from a C++ compiled .exe file to .txt or any other form and make use of the result (I have no C++ skills at all)

Answer 1

If anyone is interested how I fixed the problem. I just created a vbs linking to the .exe

    Set objShell = CreateObject("WScript.Shell")
Set objWshScriptExec = objShell.Exec("detectefi.exe")
Set objStdOut = objWshScriptExec.StdOut

dim isLegacy
dim isUefi

isLegacy = false
isUefi = false

While Not objStdOut.AtEndOfStream
   strLine = objStdOut.ReadLine

   if strLine = "Legacy" then
      isLegacy = true
   end if

   if strLine = "UEFI" then
      isUefi = true
   end if
Wend


if isLegacy then
   wscript.echo "this is legacy"

    set objShell = Wscript.CreateObject("WScript.Shell")
    objShell.Run "2TBdeploy.cmd",1,True
    set objShell = Nothing

end if


if isUefi then
   wscript.echo "this is UEFI"

    set objShell = Wscript.CreateObject("WScript.Shell")
    objShell.Run "3TBdeploy.cmd",1,True
    set objShell = Nothing

end if
