So recently, I installed Kali Linux onto my laptop, like you do, and the machine had Windows 10 on it. I decided to go with a duel boot since there were things on the Windows I wanted to still be able to use. Most notably, my writing software and music making software. However, Kali and Grub installed correctly. But Grub didn't have Windows 10 as an option. I checked and the hard drive is still there with everything in it, it wasn't overriden, it just didn't show up. My question is, how do I add Windows 10 as a boot option in grub.

And I know this isn't exactly a Kali Linux troubleshooting issue. But still, it's an issue and I'm running Kali Linux.

Thanks, Justice.
