The following suggestions are described by another moderator regarding your problem where it was solved by following the steps below

The error message Windows boot manager boot failed appears if the Master Boot Record is corrupted. The most common reasons why a Master Boot Record will be corrupted are malware infections and improper shutting down of your computer. For us to assist you, we
suggest that you repair the Master Boot Record of your Windows 10 computer. Here's a simple guide that you can follow to do it:

Press F8 while booting the system to go into the Windows Recovery Menu.

Click on Troubleshoot.

Click on Advanced options to get into Automatic Repair menu.

We need to use the Bootrec.exe tool. Click on command prompt and type in the following commands, one after the other:

bootrec /RebuildBcd

bootrec /fixMbr

bootrec /fixboot

bootsect /nt60 SYS or bootsect /nt60 ALL

Exit and now go ahead and reboot your system.

We highly recommend that you backup your Master Boot Record or create a System Recovery Disk so that in case something like this happens you don’t have to run the Windows Recovery Disk. To create a system recovery drive, just follow the steps listed below:

Press the Start button.

Type RecoveryDrive.exe.

Click Next

Once you insert the USB drive, it will start creating the Recovery on your USB drive.
