How to Create Boot Entry within Windows

To create a new boot entry, follow these steps:

1. Open an elevated Command Prompt or PowerShell.
2. Use the bcdedit command to create a new entry. For example:

   bcdedit /copy {current} /d "$New_Boot_Entry"

3. This command copies the current boot entry and creates a new one with the specified name.

How the Code Works

The script performs the following actions:

1.Check for Administrative Privileges:
The script checks if it is running with administrative rights. If not, it relaunches itself with elevated privileges.

#powershell
function Test-Admin { ... }

2.Log File Initialization:
It initializes a log file to track the script's actions.

#powershell
Copy code
$logPath = "C:\Scripts\LogFile.log"

3.Get the Current Boot Entry:
The script retrieves the currently selected boot entry from the boot manager.

#powershell
Copy code
foreach ($boot in $bootmanager) { ... }

4.Enable or Disable Features:
Based on the current boot entry, the script enables or disables the feature.

#powershell
Copy code
if ($bootEntry -eq "$New_Boot_Entry") { ... }
elseif ($bootEntry -eq "$Current_Boot_Entry") { ... }

Using Task Scheduler

To ensure that the script runs with the highest priority:

1.Open Task Scheduler. 2.Create a new task and set the following properties:

• Run with highest privileges.
• Trigger the task at system startup or on a specific event related to boot entries.
• Set the action to run your PowerShell script.

Log File

The script maintains a log file located at C:\Scripts\LogFile.log. This file records the actions taken by the script, including:

• Start and completion messages.
• Status of feature enabling or disabling.
• Any errors encountered during execution.

Usage

To use the Windows Boot Feature Manager:

1.Ensure the script is run with administrative privileges.
2.Execute the script in PowerShell:

#powershell
.\YourScriptName.ps1

Example Output

Upon execution, the log file will include entries such as:

#yaml
