To mount an ISO file on your PC's virtual drive, follow these steps:
Right-click on the ISO file you want to mount and select "Mount" from the context menu. If you don't see the "Mount" option, you may need to download and install a third-party virtual drive software, such as Virtual CloneDrive, WinCDEmu, or DAEMON Tools Lite.
If you're using the built-in Windows 10 ISO mounting feature, the ISO file will be mounted automatically and a new virtual drive will be created in File Explorer.
If you're using a third-party virtual drive software, you may need to select the drive letter you want to use for the virtual drive and click "Mount" or a similar button. Once the ISO file is mounted, you should see its contents in File Explorer just like you would with a physical disc.
To unmount the ISO file, right-click on the virtual drive in File Explorer and select "Eject" or "Unmount" from the context menu.
Note: Mounting an ISO file on a virtual drive can be useful when you want to install software or access files that are stored in the ISO file without burning it to a physical disc
