Step 2. Launch EaseUS Partition Master, and find the "Bootable Media" feature on the left. Click on it.
Step 3. You can choose the USB or CD/DVD when the drive is available. However, if you do not have a storage device at hand, you can also save the ISO file to a local drive, and later burn it to a storage media. Once made the option, click the "Create" button to begin.
- Check the Warning message and click "Yes".
Step 4. When the process finishes, you'll see a pop up window, asking if you want to restart computer from the bootable USB.

This is how EaseUS Partition Master works to recover a deleted partition. For beginners, it's easier to use without typing any command lines during the process.
Fix 2. Run Command Prompt
If you prefer a manual approach, running Command Prompt can be an effective way to restore the deleted boot partition. It is a powerful tool that lets you execute commands to repair your system's boot configuration.
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.
Command Prompt is a little difficult to use for beginners, so do not forget to share this article to help more users.
Fix 3. Reinstall Windows 10
The most straightforward solution to restore your system might be reinstalling the Windows from scratch. While this method may require more time, it creates a new boot partition and ensures your system is fully operational.
Doing this will overwrite your existing installation, but it is useful when the boot partition is beyond repair. Below are the elaborate steps to reinstall OS to fix the accidentally deleted boot partition in Windows 10:
Step 1. The first thing you will need to do is download the official ISO file for Windows and create a bootable USB with media installation. Once you are done doing that, attach it to the targeted system and boot from the drive.
Step 2. As your computer booted from the USB drive, the Windows Setup screen would appear. Here, go on to select your language, time, and keyboard preferences, then click "Next." Following that, tap "Install now," and you will be prompted for a product key.
Step 3. Here, enter the key or choose "I don't have a product key" to continue with the installation. If you have had the paid version before, your Windows will activate automatically once it is installed. Then, press "Next" and choose "Custom: Install Windows only (advanced)" to perform a clean installation.
Step 4. Now, you need to delete the partition where Windows is currently installed and later select the unallocated space. Lastly, hit "Next" to let Windows automatically create the necessary partitions and begin the installation process.
