Windows installation error Bootmgr not found fix
📋 Table of Contents
The 'BOOTMGR is missing' error occurs when Windows 7 fails to load its boot manager, resulting in an inability to boot into the operating system. This issue affects users who have installed Windows 7 on their Lenovo laptops and are experiencing a black screen with the aforementioned message.
This problem can be frustrating as it prevents users from accessing their computer's operating system, making it difficult to perform essential tasks such as work, entertainment, or communication.
🛑 Root Causes of the Error
- The primary cause of this error is usually due to a corrupted Master Boot Record (MBR) or a damaged Windows installation. The MBR contains critical information about the boot process, including the location of the boot manager. If it becomes corrupted, the system may fail to load the boot manager.
- Another possible reason for this issue could be a malfunctioning hard drive or a failing SSD, which can cause the operating system to fail to recognize its own files and directories.
🚀 How to Resolve This Issue
Boot Repair using System Recovery Options
- Step 1: Press the F2 key repeatedly while powering on the laptop until the boot menu appears. Select 'Repair Your Computer' from the boot options.
- Step 2: Click on 'Troubleshoot' and then select 'Advanced options'. From there, click on 'Boot options' and ensure that 'Windows Boot Manager' is selected as the default boot option.
- Step 3: Now, click on 'Load Driver' and select the Windows installation media (CD/DVD or USB drive). Click 'Next' and follow the prompts to complete the process.
Boot Repair using a Linux Live CD/USB
- Step 1: Download a Linux Live CD/USB, such as Ubuntu or Linux Mint, and create a bootable USB drive. Insert the USB drive into the laptop and power it on.
- Step 2: Press the F2 key repeatedly until the boot menu appears. Select 'Boot from USB' and choose the Linux Live CD/USB as the boot option.
