My grub screen was not showing Windows 10 boot option. I tried the command:

sudo os-prober

but it was not able to detect Windows 10. Then I made the following changes to 40_custom file

menuentry "Windows 10 (loader)"{
    insmod part_gpt
    search --no-floppy --set=root --fs-uuid 8600-6723
    chainloader (${root})/EFI/Microsoft/Boot/bootmgfw.efi
}

I typed the uuid of /dev/sda2 in the above menu-entry and updated the grub file using : sudo update-grub

After restarting the laptop I got Windows 10 (loader) option, but after clicking it it gives error " invalid signature ".

Please find below the output of sudo fdisk -l for reference :

I am also attaching the output of sudo blkid /dev/sda2 for reference :

sda2

I also tried Boot-Repair, but it didn't work. Boot Info Script

How can I boot into Windows 10 again?
