There are a few stages involved in switching from a classic BIOS (basic input/output system) to UEFI (unified extensible firmware interface), and they may differ based on the maker and model of your particular machine. An overview of the procedure is provided here for your convenience:
It's important to note that altering your BIOS or UEFI settings may have unforeseen effects or possibly make your computer unworkable before moving on with any changes to your system's firmware. Before making any changes, proceed with caution and make a backup of any vital data.
- Verify compatibility: Determine whether the UEFI hardware on your machine is supported. It's possible that older computers lack UEFI firmware or just have a few UEFI features. To be sure, check the documentation online or on the manufacturer's website for your computer.
- Make a backup: Before making any firmware updates, it is strongly advised that you make a copy of your vital data. By doing this, you can be confident that you have a backup of your files in case something goes wrong.
- In order to access the BIOS or UEFI settings, restart your computer and search for a certain key or key combination at startup. The keys Del, F2, F10, or Esc are frequently used. The right key(s) to access the settings can be found on the manufacturer's website or in the manual that came with your computer.
- Enter the BIOS/UEFI settings: Once there, seek out a setting pertaining to the boot mode, system configuration, or anything similar. Your motherboard and the firmware version you are using will determine the precise placement and name of the option.
- Turn on UEFI boot mode: Go to the boot mode menu and switch "Legacy" or "Legacy BIOS" to "UEFI" or "UEFI Mode." Exit the BIOS/UEFI settings after saving the modifications.
- Verify the boot mode switch. Your machine should now boot in UEFI mode once you restart it. This may be confirmed by going back into the BIOS/UEFI settings and seeing if the boot mode is still set to UEFI.
- Reinstall the operating system (optional): To guarantee optimal compatibility and performance, switching the boot mode from Legacy to UEFI may require reinstalling the operating system. Although optional, this step is advised for the best outcomes.
- Install a UEFI-compatible boot loader (optional): If you've decided to replace the operating system, you might want to install a boot loader that is UEFI-compatible, such as GRUB2 or Windows Boot Manager, to control the boot process efficiently.
Keep in mind that the methods listed here are only general suggestions; depending on the maker and model of your computer, other stages and options may apply. For specific instructions customised to your system, always go to the manual or manufacturer's website that came with your computer.
To convert an MBR (Master Boot Record) drive to a GPT (GUID Partition Table) drive Without data Lose, you can follow these steps:
Important Note: Converting MBR to GPT will erase all the data on the disk, so make sure you backup important files before proceeding.
- Press Windows key + X and select "Disk Management" from the menu.
- Right-click on the disk you want to convert and select "Convert to GPT Disk".
- Click "OK" to confirm the conversion.
- Disk Management will display a warning message indicating that the conversion will erase all data on the disk. If you have backed up your data and are sure you want to proceed, click "Yes" to continue.
- After the conversion is complete, you should see a green check mark next to the disk indicating that it is now a GPT disk.
Alternatively, you can use the command line utility "Diskpart" to convert the MBR drive to GPT. Here are the steps:
- Press Windows key + X and select "Command Prompt (Admin)" from the menu.
- Type "diskpart" and press Enter.
- Type "list disk" and press Enter to display all disks connected to your computer.
- Identify the disk you want to convert to GPT and type "select disk X" (where X is the number of the disk you want to convert) and press Enter.
- Type "clean" and press Enter to erase all data on the disk.
- Type "convert gpt" and press Enter to convert the disk to GPT.
After the conversion is complete, you can create new partitions on the disk and restore your data from the backup.
To convert an MBR drive to GPT using MiniTool Partition Wizard, you can follow these steps:
- Download and install MiniTool Partition Wizard on your computer.
- Launch the program and select the disk you want to convert from MBR to GPT in the disk map.
- Right-click on the selected disk and choose "Convert MBR Disk to GPT Disk".
- A pop-up window will appear with a warning message stating that converting the disk from MBR to GPT will delete all data on the disk. If you have backed up your data and are sure you want to proceed, click "OK".
- Click "Apply" at the top-left corner of the program window to confirm and apply the changes.
- MiniTool Partition Wizard will start converting the disk from MBR to GPT. This process may take some time depending on the size of the disk and the amount of data on it.
- Once the conversion is complete, the program will display a message indicating that the conversion was successful.
After the conversion is complete, you can create new partitions on the disk and restore your data from the backup.
Note that MiniTool Partition Wizard also provides a feature called "Convert GPT Disk to MBR Disk" that allows you to convert a GPT disk to MBR. However, the same warning message applies, and all data on the disk will be deleted during the conversion process. Make sure you backup important files before proceeding.
