This question is an exact duplicate of:
I have installed Kali Linux with the separate /home directory option. Problem is /home directory have larger space, and shortly after I wanted to merge it to my main kali partition.
So since I can't merge it with Gparted inside the working OS, I deleted my /home partition by using Windows Disk Management, thinking that I would be able to merge it after..
How unfortunate I am because now I can't login to Kali and even to my Windows. I can boot to windows until login screen, but after I entered my password it's a black screen.
My question are: - What is inside that /home directory so it can make me unable to login? Because before I deleted it, I've checked inside and it's empty..
Why does deleting the partition that belong to other OS can cause my Windows experience a black screen error after login?
How can I login to my kali again?
Thanks in advance.
