Double-click the ISO file. It will appear as a new drive on your desktop or in the Finder sidebar. 2. Run the Installer Once the ISO is mounted: Open the "new" drive that appeared. Look for a file named setup.exe , install.exe , or start.app .
Double-click that file to begin the software installation process, just as you would with a physical disc. 3. Burn to a USB or DVD (For Bootable Software) Use Iso To Install Software
If you are using the ISO to install something like or Linux on a completely different computer, mounting it won't work because you need the computer to start (boot) from that file. Double-click the ISO file
Plug the USB into the target computer, restart it, and tap a key (usually F12, F2, or Del) to enter the Boot Menu. Select the USB drive to start the installation. 4. Eject When Finished Run the Installer Once the ISO is mounted:
On modern computers (Windows 8/10/11 and macOS), you don’t need extra software to "open" an ISO. You simply it, which makes your computer treat the file like a disc you just plugged in.
Drag the mounted drive icon to the Trash (which turns into an Eject symbol) or click the Eject icon in Finder.
Use a tool like Rufus (Windows) or Etcher (Mac/Linux). These apps take the ISO file and "burn" it onto a USB flash drive.
