One can install Windows on Mac with the help of the built-in Boot Camp Assistant software offered in macOS, use virtualization software like VirtualBox to install Windows inside Mac, or manually create a new partition and then install Windows without the help of Boot Camp.
If your Mac automatically downloaded the new macOS update installer, you can delete it and recover space. Click the Finder icon in the lower left corner of your screen. (You can optionally drag the app icon to the Trash on the Dock if you're more comfortable doing that.)
If you want to remove macOS completely, then there's no need to use Boot Camp at all (with that big exception of the support software, which you already have!) You can then boot to the Windows installer, choose to erase the drive completely, then install Windows on the full space - if that's what you really want.
You CAN just install Windows. Either from using the BootCamp assistant (Apps>Utilities>BootCamp) or simply by holding down OPTION (ALT) or "C" (for CD-boot) on the keyboard during boot up with the Windows disc in. Windows 7 runs amazing on my Mac Mini 2,1.

You installed Apple's new MacOS Catalina on your Mac, but you might be having issues with the new version. Unfortunately, you can't simply revert back to Mojave. The downgrade requires wiping your Mac's primary drive and reinstalling MacOS Mojave using an external drive.
How to downgrade from macOS Catalina back to macOS Mojave
- Important information for Macs with the T2 security chip.
- Step 1: Back up your Mac.
- Step 2: Create a bootable drive of macOS Mojave.
- Step 3: Erase macOS Catalina.
- Step 4: Reinstall macOS Mojave.
- Step 5: Restore data from an earlier macOS Mojave Time machine backup.
As with most macOS updates, there's almost no reason not to upgrade to Catalina. It's stable, free and has a nice set of new features that don't fundamentally change how the Mac works. That said, because of potential app compatibility issues, users should exercise a little more caution than in years past.
How to do a clean install of macOS Catalina
- Step 1: Back up your Mac.
- Step 2: Create a bootable drive of macOS Catalina.
- Step 3: Erase your hard drive.
- Step 4: Install a new copy of macOS Catalina.
The correct way to reinstall macOS Catalina is to use your Mac's Recovery Mode:
- Restart your Mac and then hold down ? + R to activate Recovery Mode.
- In the first window, select Reinstall macOS ➙ Continue.
- Agree to the Terms & Conditions.
- Select the hard drive you'd like to reinstall mac OS Catalina to and click Install.
The bottom line: Most people with a compatible Mac should now update to macOS Catalina unless you have an essential incompatible software title. If that's the case, you may want to use a virtual machine to keep an old operating system in place to use the outdated or discontinued software.
Disk Utility is an app that comes with your Mac. It's tucked away in the Utilities folder, which is found inside the Applications folder, but is easy to locate using Spotlight - which you trigger by pressing Command+Space Bar.
Try a normal restart from the Apple menu. If that doesn't work you'll need to hold the power button for around 10 seconds until it shuts down. Press and hold the power button to shut down. If the macOS Utilities screen loads upon restarting your Mac normally, it means its startup volume has failed.
There's no reason for most to update to Catalina just now. Mojave 10.14 is mature, works well, and third-party developers have worked on their apps under Mojave. The next 'point' release of MacOS Catalina, 10.15. 1, is currently in beta.
