I installed Kali onto a separate hard drive that wasn't really being used on my computer for any thing important, meaning I didn't give part of my local disk partition to install Kali. I am able to get into Kali however there are no other options in the grub menu other than the recovery mode and memtest, windows is not listed anywhere on the menu. Can someone help me fix this problem, ideally without having to reinstall windows and sorry if this is in the wrong place I wasn't sure where to post this issue.
