Changing the Boot Drive Using Windows Settings

Windows 11 provides a graphical interface to adjust the boot drive without accessing BIOS directly. This is particularly useful when you want to reboot once into another drive without permanently altering the boot order.

To change the boot drive from within Windows 11:

  • Open **Settings** and navigate to **System > Recovery**.
  • Under the Advanced startup section, click Restart now. This action will reboot the system into a special menu.
  • When the system restarts, select Use a device from the options.
  • Choose the drive or device you want to boot from, such as a different internal drive or USB device.
  • The system will boot from the selected device for that session only; subsequent restarts will revert to the original boot drive unless changed permanently in BIOS.

This method is ideal for temporary boot changes, such as troubleshooting or installing a new OS.

Using Disk Management and Command Prompt to Prepare a Boot Drive

Before changing the boot drive, it is crucial that the target drive is properly prepared with a valid system partition and boot files. Windows 11 requires the drive to have a system partition formatted with the correct file system and boot configuration.

Using Disk Management, you can verify the drive’s partitions:

  • Press Win + X and select Disk Management.
  • Check if the target drive contains an EFI System Partition (ESP) and a primary Windows partition.
  • If not, you may need to create or format partitions accordingly.

Alternatively, the Command Prompt provides tools like `diskpart` and `bcdboot` to prepare the drive:

  • Open Command Prompt as Administrator.
  • Use `diskpart` to clean, partition, and format the drive.
  • Use `bcdboot` to copy boot files from an existing Windows installation to the new drive.

Example commands:

“`
diskpart
list disk
select disk X
clean
convert gpt
create partition efi size=100
format quick fs=fat32
create partition primary
format quick fs=ntfs
assign letter=C
exit

bcdboot C:\Windows /s S: /f UEFI
“`

Replace `X` with the disk number and assign appropriate drive letters as required.

Changing the Boot Drive Using Third-Party Software

Several third-party utilities can simplify changing or cloning boot drives in Windows 11. These tools often provide user-friendly interfaces to clone existing installations or manage boot configurations.

Popular software includes:

  • Macrium Reflect: Provides disk cloning and imaging with bootable rescue media.
