Windows 10: Windows 10 Boot Manager Error Code 0xo0000098

So I am getting this error code 0xo0000098 when I try to boot into Windows 10. It says " The windows boot configuration data does not contain a valid os entry" . I tried the following things


1. Hard reset Unsuccessful because my PC does not have a reset button and there is not enough time between POST screen and error screen. Also, I don't see a Windows logo


2. Installation media > Repair your Computer >Troubleshoot > Startup Repair Before doing step 3 and after step 3 multiple time before and after. Also in advance options, there is an option that says Continue to Windows 10 Enterprise but, when I click on it, it lands me on the same error screen


3. Installation media > Repair your Computer > Troubleshoot > Command Prompt bootrec /fixboot gives error "Access is denied". Tried DISKPART and other cmd stuff with no success


4. Got ISO image of build 1703. Flashed to an 8 GB pendrive. Will not boot. Flashed again. still same error same screen with the same error code 0xo0000098


I know I can perform a custom Windows install but, its my last option.


How did this happen ?


I was modifying BCD entries with EasyBCD. I was dumb enough to not take a backup

No, I did not updated Windows or any software.


Any help is appriciated.

Windows 10 Boot Manager error 0xc000000f

Hi,

The error code you're getting might be due to corruption of some boot files which help the Windows operating system to boot or load on the computer. We suggest performing a Startup repair on your computer. It will help to repair the master boot record to
get things up and running again.Kindly check the steps below:

• To access the recovery environment, turn your computer on and off three times. While booting, make sure you turn off the computer when you see the Windows logo.
  
• Once you're in the recovery screen, click on Advanced options.
  
• Click on Troubleshoot, then Advanced options.
• Lastly, select Startup Repair.

Let us know if you have any other questions.
