This method involves a series of commands that must be entered carefully to avoid further complications. Below, we'll guide you through the exact steps needed to recover your accidentally deleted boot partition in Windows 10:

Step 1. You will need to create a Windows installation disk using a USB and reboot your computer with it to initiate this procedure. Once the system is rebooted, utilize the "Shift + F10" keys to get access to Command Prompt access "diskpart."

Step 2. Once in DiskPart, run the command "list disk" to select the disk with the deleted boot/EFI partition by running the "select disk M" command. Now, view the available partition through "list partition" and follow it by typing "create partition efi" to hit Enter.

Step 3. This command will recreate the deleted EFI partition, and you can also define its size here. Next, run the command "format quick fs=fat32" to format the partition to FAT32. Now, confirm the creation of the new partition through "list partition" and utilize "exit" to move out of DiskPart.

Step 4. After that, typing in and executing the "bcdboot C:\windows /s X" command becomes a necessity to copy the required boot files to your newly created partition. Within this command, "C" stands for the volume with Windows OS, and "X" is the EFI partition letter.

Step 5. Go on to unplug the installation disk to reboot your system after the copying process is complete. You will be required to turn on the system using the installation flash drive to launch CMD by employing the "Shift + F10" key combo.

Step 6. Here, start by running the command "bootrec /fixmbr" and follow it by accessing "diskpart." Next, select the disk with the boot files using "select disk K" and run the "list partition" command. Then, choose the Windows OS partition by using "select partition V" and mark it as "active."

Step 7. With that done, you will need to leave DiskPart by utilizing "exit" and running the "bootrec /fixboot" command to start repairing. Execute the "bootrec /rebuildbcd" command at the end to view the end of the procedure for normal system boot.
