Hello Ajay,

Welcome to Microsoft Community forum.

This issue occurs when the Windows Boot Manager (Bootmgr) entry is not present in the Boot Configuration Data (BCD) store or if the Boot\BCD file on the active partition is damaged or missing.

I would suggest you to perform Automatic Repair and check if it helps.

1. Insert the USB recovery media and restart the computer.
2. Press F12 key (typically this is F12, but it can differ between computer manufacturers) and choose the drive that you inserted the installation media into.
3. Once the Windows Setup window appears, follow these steps:
4. Click next and select Repair your computer.
5. You will then see a blue screen and an option to choose.
6. Choose the option Troubleshoot and select advanced options.
7. You may choose Automatic Repair from Advanced boot option.
