Grub unable to find windows 10

I installed kali linux 2019.1a with Windows 10. After successful installation, grub doesn't shows windows 10.
And after making changes in Bios (enabling eufi) windows 10 starts, but again after disablinh eufi grubs only shows kali Linux.
Tried os-prober bad update-grub, but both fails to recognized windows 10.

did you update-grub and update-grub2 ??

It's because you installed kali in legacy BIOS mode. What made you to disable UEFI to install Kali?

Delete Kali partition and Install again in UEFI.
