Windows 10: Boot sector missing after each update of configuration KB5035942 using 23H2

I am using Windows 11 Home Version 23H2. The startup loading of my PC has been in trouble in missing boot sector within one or few days since 2 May. Fortunately, the Copilot taught me how to rebuild it and boot it up again every time I got the same booting problems. Missing boot sector was happened yesterday and was fixed. There was no problem this morning until shutting down. When reopening it again at noon, the same problem came back again. I noticed that the problems came from every update of Windows configuration KB5035942. Could you tell what has gone wrong and h

Missing Boot Sector

Hello, I have gotten into some complications with my Windows 10 install with missing a boot sector after performing these steps:-

1. Cloned my Windows installation with Acronis True Image tool from my hard drive to my m.2 SSD

2. Deleted partitions and formatted the hard drive, to be used as storage

3. Result: Missing boot manager error

Is there a way to transplant a working boot sector in my m.2 SSD from either the hard drive or from a bootable USB stick without performing another format and OS install on the drive?

Help would be much appreciated, thank you so much.

Windows update KB5035942 installs every day

Thanks for your suggestions. I had previously tried the Troubleshooter and SFC & DISM steps. I read about Microsoft update KB5036567, which claims to fix issues related to KB5035942. I downloaded it from the Microsoft Catalog, and used the command dism /Online /Add-Package /PackagePath:"CAB location" to install the update. The dism ran very quickly and indicated success. I restarted my PC but do not see KB5036567 in the update history list. So I'm not sure if I really installed the update, especially given how quickly the dism ran.
