ICS allows instalaltion not only from CD-ROM, but also from USB flash-drive.
A special application is needed for image recording. It could be downloaded here.
In the new opened window - specify the path to ISO-images and flash-drive followed by OK. Writing to flash drive process will begin.
Once finished - plug the USB flash drive into the USB port on ICS installation computer and make sure to specify USB-flash drive as first booting device in the system BIOS.
Warning: not all motherboards are supporting installation from USB-flash drive!
Once the image boots from the flash drive - normal installation process will start as normal.
