yesterday I tried to dual boot Windows and Ubuntu but then when I restart my laptop, I didn't start Windows but it ran Ubuntu immediately.
Then I knew I just accidentally removed Windows boot manager. When I used sudo fdisk to check the disk I still saw my I basic data. Also, I saw a local disk which has my old Windows data on the 'other locations'. Please help me to recover Windows (you can remove Ubuntu if necessary).
I know many people have asked the same questions like me but from yesterday until now I cannot fix this. Ask if you want to see further configuration or disk on my Ubuntu.
Edit: One friend told me to use sudo os-prober to indentigy windows 10 install and then use sudo update-grub to update the GRUB. After typing os-prober, it said
/dev/nvme0n1p1@/EFI/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi
but then when using update-grub. it cannot find windows but rather

I also check check /etc/default/grub but there is no GRUB_DIASBABLE_OS_PROBER.
