Restoring Windows 10 PRO: Mismatched GPT-MBR Partition - A Step-by-Step Guide
If you're a Linux guy, like me, who has a Windows 10 PRO system that seems to be running slowly, and you suspect that the ESD (electronic software distribution) on your SSD (solid-state drive) might be questionable, you may want to consider restoring your Windows 10 PRO system to its original state.
However, if you encounter a mismatched GPT (GUID Partition Table) and MBR (Master Boot Record) partition error during the restoration process, don't worry - this step-by-step guide will help you resolve the issue and successfully restore your Windows 10 PRO system.
What is GPT and MBR, and why do they matter?
GPT and MBR are different partition styles used to organize data on a hard drive. GPT is a newer standard that offers several advantages over MBR, such as support for larger drive sizes and more partitions. However, if you're trying to restore a Windows 10 PRO system, you might encounter a mismatched GPT-MBR partition error.
This error occurs because the restoration process expects the partition style to be MBR, but your system is using GPT. To resolve this issue, you'll need to convert the partition style from GPT to MBR.
Step-by-step guide to restoring Windows 10 PRO with a mismatched GPT-MBR partition
- Backup your data: Before you begin, make sure to backup any important data on your system to an external drive or cloud storage service.
- Access the Windows recovery environment: To do this, restart your computer and press the F11 key (or the key that corresponds to your system's boot menu) during startup. Then, select the "Troubleshoot" option and choose "Advanced options." Finally, select "Command prompt" to open the command prompt window.
- Convert the partition style from GPT to MBR: Enter the following command in the command prompt window and press Enter:
mbr2gpt /convert /disk:0This command will convert the partition style from GPT to MBR on the first disk in your system.
- Exit the command prompt window: Type "exit" in the command prompt window and press Enter to close the window.
- Restore your Windows 10 PRO system: Follow the on-screen instructions to restore your Windows 10 PRO system. During the restoration process, you should no longer encounter the mismatched GPT-MBR partition error.
