For various reasons, you may need to remove unsed Windows Boot Manager entries. You can follow the steps outlined in this article to make it easy to delete useless entries of Windows Boot Manager.
The Windows Boot Manager (BOOTMGR) plays a vital role in initiating the Windows operating system. It serves as a small but crucial piece of software loaded from the volume boot code, which is part of the volume boot record. Its primary function is to enable the booting of Windows 10/8/7 or Windows Vista OS.
To function correctly, BOOTMGR relies on the Boot Configuration Data (BCD) store, a registry-like database that contains essential configuration data. This database has replaced the boot.ini file, previously utilized in older Windows versions like Windows XP.
The BOOTMGR file itself is both read-only and hidden, residing in the root directory of the partition. Moreover, it is marked as "Active" in Disk Management. In many Windows PCs, this partition is designated as "System Reserved" and does not have a drive letter assigned to it.
In cases where there is no "System Reserved" partition, the BOOTMGR can be located on the primary hard drive, typically labeled as the C drive. When booting, the boot manager will execute winload.exe, the system loader responsible for continuing the Windows boot process.

These unused entries can clutter the boot menu, making it more challenging to select the correct operating system during startup.
◤ Boot time optimization: Having unused entries in the boot menu can slightly increase the time it takes for your system to boot up. When the boot manager presents a list of options, it needs to check the validity of each entry, even if it's not in use. Removing unused entries streamlines the boot process, leading to faster startup times.
◤ Avoiding potential conflicts: In some cases, having multiple entries for the Windows Boot Manager could lead to confusion and potential conflicts. For instance, if you inadvertently select an old or unused entry, it might cause errors or prevent your system from booting properly.
◤ Disk space management: While the space occupied by unused boot entries is relatively small, it's still an unnecessary allocation of disk space. Cleaning up the boot menu ensures that only relevant and active entries remain, optimizing disk usage.
