Windows 10: Windows bootloader gone

HI, since i updated to windows 11, the windows bootloader option disappeared from my bios options to boot. I have dual boot with ubuntu and the only way to access windows is by the grub. I want to uninstall Ubuntu, but i'm afraid it can cause trouble. I've tried repairing the bootloader but it shows an error at trying to copy my boot files. I've also tried using EasyBCD, but my bios is set-up as UEFI, so I can't do a thing. I don't know what else to do, please help. My disks are GPT, both of them.This are my partitions, the one on top is the main disk, a ssd, and the one below is for storage,

:)

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

How To Fix The Windows 10 Bootloader

THANK YOU. This solved it. I think this was mentioned earlier by you or someone else perhaps but I've messed around with it enough now where I vaguely understood what the commands were doing. I actually had to delete the partition, recreate it, and re write the BCD as you suggested in Step 3.

Shoutout to @topgundcp I'm sure that last method you suggested would have worked too, but now I understand how to do it manually, so I learned something.

Also, thank you @NavyLCDR for your help as well.

I have ONE last question, any SAFE way to remove the old ubuntu EFI entries that are present in my UEFI as boot options?

edit: Nvm, figured it out. For anyone else wanting to know how to remove old EFI boot entries, use "EasyUEFI" it is super easy. Took like 10 seconds after install. I DID have two identical looking EFI's for my samsung ssd, one of them, in the details, showed that it had no file path. I assumed that was my old broken one and deleted it, must have been correct bc my computer boots up perfect.

Thanks!!!
