Install using the 'createinstallmedia' command in Terminal:
1- After downloading, unzip to get the installer file and place it into the application folder, connect the USB flash drive or other volume you're using for the bootable installer. Make sure that it has at least 15GB of available storage and is formatted as Mac OS Extended.

2- Open Terminal, which is in the Utilities folder of your Applications folder.
3- Type or paste the following command in Terminal. These assume that the installer is still in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.

sudo /Applications/Install\ macOS\ --volume /Volumes/MyVolume

4- Press Return after typing the command.
5- When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.

6- When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created.

7- When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.

Use the bootable installer
After creating the bootable installer, follow these steps to use it.
1. Connect the bootable installer to a compatible Mac.
2. Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
3. Choose your language, if prompted.
4. A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
5. Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

Important Notes
(Before installing any upgrade, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available)
(If you're using a Mac notebook computer, plug it into AC power)
(To upgrade from Lion or Mountain Lion, first upgrade to El Capitan, then upgrade to Catalina)
(If your Mac running Mojave then it can run Catalina)
(You can install macOS Catalina or any other macOS version on a Windows PC using VirtualBox or VMWare and in this case you will need to convert the .dmg file to .iso file)
(This is my own advice, if you are such a gamer then DO NOT use macOS Catalina. Most of games does not run on this macOS so if you are a gamer stay with macOS 10.13 High Sierra)

@NobleWolf You can try using Power Iso. It helps you to convert a .DMG file to .ISO.
You can download Power Iso on TeamOS forum through THIS LINK .. Thanks to @MillerGrey .
