Welcome to LQ! I'm not familiar with the equipment you mention, however, if you are attempting to boot from a USB device, that would only be an option if your BIOS supports it. Reboot, get into BIOS, and look at the boot choices that appear -- if booting from a USB device is an option, move it to the top of the list, save the changes, and you should be ready to go. If it does not appear as a boot option, there is no workaround (at least none that I'm aware of)
Additionally, there is a possibility that the CD's you purchased are defective, but I would guess this is probably not the case. However, you can download those same Live CD's yourself, for free, from places like our own LQ ISO
, or the distro's websites, then burn them yourself and see if you have better luck.
If you decide to do this, make sure to run the MD5SUM against the downloaded file to verify that it is not corrupted, before you burn it to a CD (as there is no sense in creating coasters unnecessarily). Basically this is done by simply running the following command
where <filename> is the actual ISO file name. The output will be a long series of letters and numbers, which should be compared to the reference number (the site you downloaded the ISO from willl have it) Unless those MD5SUM's match perfectly, the image has been corrupted and should be discarded. Lastly, when you burn the ISO to the CD, you must burn it as an image -- you cannot just do a drag-and-drop copy, or burn it as a regular data file. You may already know all of this, but I've included this in case you didn't. Good luck with it either way -- J.W.
