    Can't boot into Win 10 after installing Kali to seperate partition

    I installed Kali using a live usb on a system with Windows 10 already installed. I used gparted to shrink the windows partition and used the new unallocated space to install kali. In the setup process it did not detect the windows os, and now grub only shows kali. I have tried several tutorials on how to add windows 10 to the grub menu, but every time it says invalid signature when choosing that menu option. The below output shows a EFI partition and a BIOS partition, could that be an issue?

    Code:
    root@cozen:/sys/firmware# fdisk -l
    Disk /dev/nvme0n1: 465.8 GiB, 500107862016 bytes, 976773168 sectors

    Did you changed the Boot settings to a useless option Legacy BIOS before installing kali?

    HI,
    I had the same issue, to resolve this problem use Boot- Repair

    The easiest way to use Boot-Repair is to create a disk containing the tool (eg Boot-Repair-Disk, a disk starting Boot-Repair automatically), and boot on it.

    Remark : it is recommended to install the ISO on a live-USB (eg via UnetBootin or LiliUSB or Universal USB Installer). Do not burn it on a DVD if your computer has Windows8 pre-installed, or if your boot is in EFI mode.

    For further guidance visit: https://help.ubuntu.com/community/Boot-Repair
    This is the best way
