Dual-boot grub boot-repair issue

Hello there,

I tried to install kali alongside windows and did it wrong probably. Now whenever I boot, grub loader sees only Kali and Free-DOS and doesn't see Windows.

I can still see the Windows partition in Kali and access the files however.
Searched online for a solution and saw that boot-repair could help me, however because some new update issue I cannot install it under Kali directly( see below link, it doesnt work for me).]

Long story short, I downloaded the iso version of boot-repair and tried to burn it onto a live-usb, but it doesn't load. All I get is a black screen with a terminal line running where I can't do anything.
I burned the iso using the terminal and the command below.
sudo dd bs=4M if=file.iso of=/dev/sdc
I burned the iso using unetbootin a couple of times and the same issue.

Any ideas? am I doing something wrong? How can I burn the iso disk to a live USB to run boot-repair? Or any other alternatives?

PS: first time linux user, I have no idea what am I doing so please be patient with me.

This is my output for running sfdisk -l.

sfdisk -l

If you have one, try using your windows disk/iso to boot and repair your windows install, then use your kali install disk live to reinstall grub.

kali is a forensics system - hardly what I'd recommend for a first time user.
Being Debian based you should be able to simply run this from a terminal to get the grub cfg file rebuilt to include Windows (may need root/sudo). No need for boot-repair - which often doesn't anyway
As for the liveCD, I'd guess the iso is bad - but I didn't see a way to verify it. The dd command you used should be ok for a hydrid iso.
