Right-click the ISO file and select Mount . A new drive letter (like D: or E: ) will appear in "This PC."
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 . Use Iso To Install Software
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 Right-click the ISO file and select Mount
Once the software is installed, you should "unmount" the file so it’s no longer taking up a virtual drive slot. Plug the USB into the target computer, restart
Drag the mounted drive icon to the Trash (which turns into an Eject symbol) or click the Eject icon in Finder.
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.
Use a tool like Rufus (Windows) or Etcher (Mac/Linux). These apps take the ISO file and "burn" it onto a USB flash drive.
