I faced a problem with my laptop, as it couldn’t reach the Windows Recovery Environment menu when I attempted to select advanced startup. The only choice accessible to me is UEFI Firmware Settings, which leads to the BIOS Menu. It can boot into Windows and function normally (I think?) but I can't access troubleshooting options like safe mode. I worry that if my laptop gets into serious trouble later on, I may have to do a full reinstall because of this.
I've tried looking up solutions online and here are things that I tried:
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
reagentc.exe
through Command Prompt It gave me the error bcdedit: The boot configuration data store could not be opened
I think my problem is similar to this thread: https://answers.microsoft.com/en-us/windows/forum/all/reagentcexe-operation-failed-2/c08a3df3-0243-4cda-984e-86e9f84e01c1
But it seems too complicated for me to follow along, hence why I am asking a separate question.

Please boot from the USB setup disk. To do so, you may need to change the boot order in the BIOS/UEFI settings. Consult your system or motherboard manual to learn how to access the UEFI settings for your model.
On the Windows Setup language selection screen, press Shift + F10 to enter Windows RE Command Prompt.
In Windows RE, click Troubleshoot, Advanced Options, Command Prompt.
In the WinRE Command Prompt, type the following commands:
diskpart
select disk 1
list part
select part 1
assign letter=Y
list vol
exit
Take photos of the output screen using your phone and share the images here. Don't quit WinRE yet. Two more commands need to be run.
Now, run these commands:
xcopy /h Y:\EFI\Microsoft\Boot\BCD F:\
format Y: /fs:FAT32 /q
bcdboot F:\Windows /s Y: /f UEFI
Post the output.
Note:
When you run the format command, you'll be prompted to enter volume label. Type EFI and press Enter.
