To test the integrity of an ISO image, append the [option]#rd.live.check# to the boot loader command line. Note that this option is used automatically if you select the default installation option from the boot menu (`Test this media & install Fedora`).
Booting Your Computer in Rescue Mode
You may boot a command-line Linux system from an installation disc without actually installing {PRODUCT} on the computer. This enables you to use the utilities and functions of a running Linux system to modify or repair already installed operating systems.
To load the rescue system with the installation disk or USB drive, choose `Rescue a {PRODUCT} system` from the Troubleshooting submenu in the boot menu, or use the [option]#inst.rescue# boot option.
Specify the language, keyboard layout and network settings for the rescue system with the screens that follow. The final setup screen configures access to the existing system on your computer.
By default, rescue mode attaches an existing operating system to the rescue system under the directory `/mnt/sysimage/`.
