Changing boot device before reboot

[forthewin]

I am running AuoIt ver. 3.3.8.1

I looked around for ways to do this, but I haven't found anything yet. So, I just decided to take a wack at it for a project I'm working on. Here is the code that I have.

#include
#Include-Once
#RequireAdmin

Func _CreateBootEntry()

Local $Drive
Local $ScriptPath = @ScriptDir
$Drive = StringRegExp($ScriptPath, "([[:alpha:]]:)", 1)

Msgbox(4096, "Drive", $Drive[0])

RunWait("bcdedit.exe /create {USB} /d ""USB Boot""", "", @SW_HIDE)
RunWait("bcdedit.exe /set {USB} ramdiskdidevice partition= " & $Drive[0], "", @SW_HIDE)
RunWait("bcdedit.exe /set {USB} ramdiskdipath \boot\boot.sdi", "", @SW_HIDE)
RunWait(@ComSpec & " /c bcdedit.exe /create /d ""USB Boot"" /application OSLOADER > C:\GUID", "", @SW_HIDE)

$File = FileOpen("C:\GUID", 0)
$CurrentConfig = FileOpen(@HomeDrive & "\CurrentConfig.xml", 1)
$Contents = FileRead($File)
$GUID = StringRegExp($Contents, "(\{.*\})", 1)

FileWriteLine($CurrentConfig, "" & $GUID[0] & "")
RunWait("bcdedit.exe /set " & $GUID[0] & " device ramdisk=[" & $Drive[0] & "]\sources\boot.wim,{USB}", "", @SW_HIDE)
RunWait("bcdedit.exe /set " & $GUID[0] & " path \windows\system32\winload.exe", "", @SW_HIDE)
RunWait("bcdedit.exe /set " & $GUID[0] & " osdevice ramdisk=[" & $Drive[0] & "]\sources\boot.wim,{USB}", "", @SW_HIDE)
RunWait("bcdedit.exe /set " & $GUID[0] & " systemroot \windows", "", @SW_HIDE)
RunWait("bcdedit.exe /set " & $GUID[0] & " winpe yes", "", @SW_HIDE)
RunWait("bcdedit.exe /set " & $GUID[0] & " detecthal yes", "", @SW_HIDE)
RunWait("bcdedit.exe /displayorder " & $GUID[0] & " /addlast", "", @SW_HIDE)
RunWait("bcdedit.exe /bootsequence " & $GUID[0], "", @SW_HIDE)

EndFunc

The script is supposed to be run from the bootable device. It can be a CD, DVD, or USB. The commands work if you run them from an elevated command prompt, but they do not work from the code I have listed here. I will continue to work on it, but any assistance is greatly appreciated. Also, hopefully someone else will find this useful. It only works in Windows Vista and newer. You would have to modify the Boot.ini in Windows XP.

Have you tried replacing all the RunWaits with FileWrites to a log to see if everything is syntactically correct?

So, here is the answer for anybody who stumbles across this in the future. I meant to come back a little sooner and update this.

RunWait("bcdedit /set {ramdiskoptions} ramdisksdidevice partition=" & $fDrive[0], "", @SW_HIDE)

If StringRegExp($Contents, "(?i)successfully", 0) Then

   $GUID = StringRegExp($Contents, "(\{.*\})", 1)

   RunWait("bcdedit /displayorder " & $GUID[0] & " /addlast", "", @SW_HIDE)

   RunWait("bcdedit /bootsequence " & $GUID[0], "", @SW_HIDE)

Else

   MsgBox(16, "Error", $Contents)

As it turned out, Larry was correct in guessing that the syntax was incorrect. The commands were hardcoded incorrectly.
