ssd Hard drive is a mess of partitions

The best option is to erase the whole physical SSD before installing macOS. If this is an Intel Mac, then erase the physical drive as GUID partition and MacOS Extended (Journaled) if you are installing up to macOS 10.13, otherwise erase the whole physical drive as GUID partition and APFS (top option) for installing macOS 10.14+.

With macOS 10.13+ you need to click "View" within Disk Utility and select "Show All Devices" so that the physical drive appears on the left pane of Disk Utility. If you are installing macOS 10.6 to 10.10, then you need to partition & format the drive by using these instructions:

I'm a bit confused by the Apple Partition Map listed for your internal drive which was only used with PPC Macs.

Use the Disk Utility GUI. The "diskutil" command is complex and can take some practice to use it. I provided all the information you should need, but if you have a problem using the Disk Utility GUI, then please provide us the exact model of the Mac and the OS you are attempting to install. Plus provide the exact error you are receiving and any relevant details.

Sometimes when using the Disk Utility GUI you may need to make two attempts to properly erase the physical drive (some weird bug with Disk Utility).

Recovery mode creates about 25 RAM disks to hold temporary items so that your boot drive is free to be erased or repaired. They will All be removed when you can restart in regular mode.

If you don't like what it looks like, don't watch it from Recovery
