Can I convert mbr to gpt during Windows installation without data loss
Recently, when I was installing Windows, my hard disk was in MBR format, but I wanted to convert it to GPT format so that it can support larger hard disk capacity and use UEFI boot. I saw online that...
Of course! In addition to using the diskpart tool from the command line, there are other ways to convert mbr to gpt during Windows installation.
If your computer already has Windows installed and you want to convert an existing MBR to GPT format, you can do this in the Windows Recovery Environment. Although this method does not involve converting during installation, if you already have Windows installed and want to convert the disk format, you can follow these steps:
- Hold down the Shift key while starting your computer and click Restart. This will bring you to the Windows Recovery Environment (WinRE).
- In the WinRE interface, select Troubleshoot -> Advanced options -> Command Prompt.
- Use the diskpart tool in the command prompt to convert the disk format. The steps are the same as before using the command line method: list disk -> select disk 0 -> clean -> convert gpt.
This method allows you to convert the disk format on a system that already has Windows installed, but it also requires deleting all partitions on the disk, so backups are important.
