In earlier versions of Windows, you had to reinstall the entire operating system to convert from legacy BIOS or Master Boot Record (MBR) to UEFI or GUID Partition Table (GPT). However, in Windows 10, Microsoft introduced a new and simple utility called MBR2GPT that allows you to convert from legacy BIOS to UEFI with just two commands.
Thus, you can convert the legacy BIOS to UEFI in Windows 10.
In this article, Niketrainers.com.co will tell you:
Things you need to know beforehand
While converting legacy BIOS to UEFI in Windows 10 is easy, there are a few things you need to know and do before continuing.
1. Converting legacy BIOS to UEFI does not result in data loss. However, as a precautionary measure, do a system backup.
2. You should be using Windows 10 v1703 or above. If you are unsure, pressWygrać+R, politewinver
and press Enter. The second line should say “version 1703” or higher. For example, at the time of this writing, the latest version of Windows 10 is v1809.
3. The disk you are trying to convert cannot have more than three partitions. If you have more than three partitions on your Windows 10 installation disk, connect or delete any excess partitions.
4. If you are using BitLocker to encrypt your system, decrypt the drive and disable BitLocker protection before starting the conversion process. With BitLocker protection enabled, Windows 10 cannot convert the drive from legacy BIOS to UEFI.
5. After conversion, you may need to change your motherboard firmware settings from Legacy BIOS to UEFI. Depending on the motherboard manufacturer, the procedure for changing from one to the other will be different. Have the motherboard’s instruction manual handy to make your job easier.
Check if you are using an older BIOS version
The last thing to check is if you are using an older BIOS. After all, the conversion doesn’t make sense if you’re already in UEFI.
To find out, search for “Create and Format Hard Disk Partitions” in the Start menu and press Enter to open the built-in disk management utility. Now right click on the Windows installation disk and select “Properties”.
In the properties window, go to the “Volumes” tab. In this case, if you can see “Master Boot Record (MBR)” next to “Partition Style”, then you are in an older BIOS version.
Convert legacy BIOS to UEFI
After confirming that you are running the older BIOS version and creating a system backup, you can convert the older BIOS to UEFI.
1. To convert, you need to access the command prompt from Advanced Windows startup. To do this, pressWygrać+X, go to “Shut Down or Logout” and click the “Restart” button while holding down theZmianaKey Code button.
2. The above action will restart the system and display the Advanced Startup screen. Here, go to “Troubleshooting -> Advanced Options” and select “Command Prompt”.
3. The first thing we need to do is validate the disk we are trying to convert. Type the following command and press Enter.
If you see the message “Verification Successful”, you can proceed to the next step. If you see any errors, your disk or system may not meet the conversion requirements.
4. After checking the disk, run the following command.
Once booted, Windows 10 will start the conversion process, that is, add all the necessary UEFI boot files and GPT components, and then update the boot configuration data.
5. Now restart the system, run the motherboard firmware setup screen and change it from Legacy BIOS to UEFI. The procedure for changing from legacy BIOS to UEFI depends on the motherboard manufacturer. Please refer to the manual for exact steps.
6. After Windows 10 starts, you can check whether it is converted or not. As before, open the disk properties window in the disk management utility and go to the “Volumes” tab. Here, “GUID Partition Table (GPT)” should appear next to “Partition Style”.
