I tried dual booting Kali Linux on an existing Arch Linux and I may have formatted the home partition for Arch in the process. So I was wondering is there any way at all that I can get Arch to run again fully without installing it all over again?
Is there a way to get Arch to run fully after deleting the home partition?
arch linux;home
Home partition is not required for system to be operational. However, many programs store configuration files in home directory. This might be the problem you are encountering. In this case, the simplest solution would be to use backup(which each user should have). If you don't have backup for some reason, you can resort to reconstructing crucial files(it will require some googling), or you can reinstall your programs, hoping that they will put some default configuration by themselves, so you can edit it later.
