This will open the Disk Management console, where you can view all connected drives and their partitions.

Once Disk Management is open, locate the internal hard drive you want to partition. Right-click on the unallocated space or an existing partition with enough free space and select Shrink Volume. This will allow you to create unallocated space for the new Windows 10 partition. Enter the amount of space you want to allocate in MB (e.g., 60,000 MB for 60 GB) and click Shrink. After shrinking, you’ll see the unallocated space appear in the Disk Management console. Right-click on this unallocated space and choose New Simple Volume to begin the partitioning process.

The New Simple Volume Wizard will guide you through creating the partition. Click Next on the welcome screen, then specify the size of the partition (use the maximum available if you want to use all unallocated space). On the next screen, assign a drive letter for the new partition by selecting one from the dropdown menu. This drive letter is essential for Windows 10 to recognize the partition during installation. Click Next to proceed.

Next, you’ll need to format the partition to prepare it for Windows 10. Choose NTFS as the file system, as it is required for Windows installations. You can also label the partition (e.g., "BOOTCAMP") for easy identification. Check the box for Perform a quick format to speed up the process, then click Next and Finish to complete the partitioning and formatting. The new partition will now appear in Disk Management with the assigned drive letter.

After creating and formatting the partition, ensure it is ready for the Boot Camp Windows 10 installation. Verify the partition is marked as Healthy and has the correct size and drive letter. With the partition prepared, you can proceed with the Boot Camp setup, where you’ll use the Boot Camp Assistant on your Mac to download Windows support software and begin the Windows 10 installation process. This partition will be detected automatically during the installation, allowing you to install Windows 10 seamlessly alongside macOS.

Verify Boot Loader: Ensure Windows Boot Manager is active and properly configured post-installation

After installing Windows 10 on your Mac via Boot Camp, it's crucial to verify that the Windows Boot Manager is active and correctly configured. This ensures that your system can properly dual-boot between macOS and Windows without issues. Start by restarting your Mac and holding down the Option (Alt) key immediately after startup. This will bring up the boot picker, where you should see both macOS and Windows as bootable options. If Windows is not listed or fails to boot, the Boot Manager may not be configured correctly.

To further verify the Boot Manager, boot into Windows 10 and open the Command Prompt as an administrator. Type `bcdedit` and press Enter to display the Boot Configuration Data (BCD) store. Look for the Windows Boot Manager entry under the "Windows Boot Loader" section. Ensure that the identifier and device values are correctly set. The device value should point to the partition where Windows is installed, typically labeled as `partitionX`, where `X` is the partition number. If the values are missing or incorrect, you may need to repair the BCD using the Bootrec tool.

Next, check the boot order in the UEFI/BIOS settings of your Mac. Restart your Mac and hold down the Option + Command + R + Shift keys to access the firmware settings. Navigate to the Boot Order or Startup Disk section and ensure that the Windows Boot Manager or the Windows partition is listed and enabled. If macOS is set as the default boot option, you can change the order to prioritize Windows if desired. Save the changes and exit to test if Windows boots correctly.

If the Boot Manager is still not functioning properly, use the Boot Camp Assistant on macOS to repair the startup disk. Open Boot Camp Assistant, select the Action menu, and choose "Repair the startup disk." This tool can automatically fix issues with the boot loader and partition table. After running the repair, restart your Mac and check if Windows appears in the boot picker and boots successfully.

Finally, ensure that the EFI partition is intact and accessible. The EFI partition contains the boot loader files necessary for Windows to start. If this partition is corrupted or missing, Windows will fail to boot. You can verify the EFI partition's health using third-party tools like MiniTool Partition Wizard or by running the Diskpart command in Windows. If issues are detected, you may need to reinstall Windows using Boot Camp Assistant, ensuring the EFI partition is correctly created during the installation process. Proper verification of the Boot Manager post-installation is essential for a seamless dual-boot experience on your Mac.
