How to Fix: Dual-booting Kali Linux and Windows 7, error with file: "\NST\AutoNeoGrub0.mbr"

Learn how to fix: Dual-booting Kali Linux and Windows 7, error with file: "\NST\AutoNeoGrub0.mbr".

Quick Answer: Try checking your system settings or restarting.

The error 'File: \NST\AutoNeoGrub0.mbr Status: 0xc000007b Info: Application or operating system couldn't be loaded because a required file is missing or contains errors' occurs when attempting to dual-boot Kali Linux and Windows 7 on a Dell computer with an SSD hard drive. This issue affects users who have installed Kali Linux alongside their current OS, resulting in an unstable boot process.

This error can be frustrating as it prevents the user from accessing both operating systems without issues. However, by following the steps outlined in this guide, users should be able to resolve the problem and regain access to their dual-boot setup.

⚠️ Common Causes

  • The primary reason for this error is that the GRUB boot loader was not installed correctly during the Kali Linux installation process. When the user chose not to install GRUB in the MBR but instead on a random partition, it may have caused issues with the boot loader's configuration.
  • An alternative cause could be that the SSD hard drive is not properly recognized by the Kali Linux installer, leading to incorrect partitioning and GRUB installation.

🚀 How to Resolve This Issue

Reinstalling GRUB from scratch

  1. Step 1: Boot into the Kali Linux live session and open a terminal. Run the command 'sudo grub-install --target=i386-pc /dev/sda' to reinstall GRUB on the SSD hard drive.
  2. Step 2: Next, run the command 'sudo update-grub' to regenerate the GRUB configuration file. This will ensure that the correct boot loader is installed and recognized by both operating systems.
  3. Step 3: Finally, reboot the system and select Kali Linux as the primary boot loader. If necessary, use EasyBCD to configure the boot loader settings and ensure that Windows 7 boots correctly.

Using a different partition for GRUB

  1. Step 1: Delete the existing GRUB installation on the SSD hard drive by running the command 'sudo grub --device-list /dev/sda5' in the Kali Linux live session.
  2. Step 2: Next, run the command 'sudo grub-install --target=i386-pc /dev/sda5' to reinstall GRUB on a different partition. This will ensure that the boot loader is installed correctly and recognized by both operating systems.
  3. Step 3: Finally, reboot the system and select Kali Linux as the primary boot loader. If necessary, use EasyBCD to configure the boot loader settings and ensure that Windows 7 boots correctly.

💡 Conclusion

To resolve the 'File: \NST\AutoNeoGrub0.mbr' error, users can try reinstalling GRUB from scratch or using a different partition for GRUB. By following the steps outlined in this guide, users should be able to regain access to their dual-boot setup and boot into both Kali Linux and Windows 7 without issues.
