I have a Toshiba 3490CT laptop with a blown Windows OS. I have a copy of SUSU 10.0 that I want to install on the laptop, but I can't get it to recognize the USB CD drive (all peripheral drives are external). I have tried using the boot menu, but that did not work. I also tried booting using Smart Boot Manager on floppy. It recognize the floppy drive, but still would not recognize the CD drive. I'm open for any suggestions....Thank you.
