Are you struggling with booting into Windows on an MBR disk where the System Reserved partition and OS Partition are the same? This article provides a step-by-step guide to resolve the issue using Windows 10 installation media.
When Windows is installed on an MBR Disk in a single partition, it means the System Reserved partition and OS Partition coexist. If you are facing boot issues in this setup, here’s how you can fix it:
Step 1: Make Windows Unbootable
- Insert Windows 10 Installation Media: Insert your USB drive with a bootable Windows installation and boot from it in Legacy BIOS Mode.
- Access Repair Options: On the initial setup screen, click on Next, then select Repair your computer.
- Open Command Prompt: Navigate to Troubleshoot > Command Prompt.
- Rename BCD File: Type cd /d C:\Boot\ and press Enter. Then type ren BCD BCD.bak and press Enter. This action will make the system unbootable, as the option ‘Continue to Windows’ will disappear.
Step 2: Fix the Boot Issue
- Insert Windows 10 Installation Media: Boot from the Windows installation media again.
- Access Repair Options: On the initial setup screen, click on Next, then select Repair your computer.
- Open Command Prompt: Navigate to Troubleshoot > Command Prompt.
- Fix MBR and Boot Files:
- Type bootrec /fixmbr and press Enter.
- Type bootrec /fixboot and press Enter.
- Type bootrec /scanos and press Enter.
- Type bootrec /rebuildbcd and press Enter.
- Exit Command Prompt: Type exit and press Enter.
Restart your computer, and you should see the option to ‘Continue to Windows’ reappear, allowing your system to boot normally.
By following these steps, you can resolve MBR boot issues when the System Reserved and OS are on the same partition.
