Can't delete partitions on Disk Utility. No CoreStorage logical volume groups found.

When I ran the command "diskutil cs list", it said No CoreStorage logical volume groups found. I am trying to delete two partitions from disk utility but the - symbol is greyed out. My goal is to have one journaled partition so I can use boot camp assistant to instal windows 7. I have a 2008 macbook. I attached a screenshot.


Boot Camp assistant tells me "The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows."


Please advise.

Internet recovery doesn’t work for me, it went to regular recovery mode. I googled to see what the issue is. It mentioned a few reasons, my Mac may be old, it’s 2008. Or running macOS older then Sierra. I am running El Capitan. Another thing, in the past I used a bootable installer, this also could be causing no internet recovery mode. I will see if I can find out and keep trying. Please let me know if you have any ideas what is causing this?
