Booting 7.4.0DVD-2014-08-01-EN.iso

[Woody Ochs]

I downloaded this code and burned it to a DVD, and all the md5s agree, but I can't get that DVD to boot on either a 64bit system or on a 32bit system. The bootloader does not recognize the cheatcodes "knoppix64" or "knoppix32", nor will it boot with no cheatcode at all. I have used Knoppix distros for ten years now but have never encountered a problem such as this. Is anyone else having such a problem?

Working fine for me Woody (at least as far as booting goes). Let me ask a few questions: Are you at least seeing the first Knoppix prompt (sounds like you are if you are trying cheat codes)? Did you burn at low speed (4x preferred, no more than 8x)? What part of North Carolina are you in (I'm near Apex)? Tell us anything else that you can that might help, like what you are trying to boot it on, did you run the testcd cheat code, just how far you are getting before it fails, and so on. I would even try the memtest boot code if you are comfortable that none of the above are issues. Do you have more than one computer that you could test your DVD on, and did you test it on multiple systems?

Thank you for your post. The problem, as you suspected, was a badly burned DVD, though K3b deemed the burn a success. I burned another DVD with Xfburn, and that disk works. I did both burns on a Wheezy 64 system, so I must now wonder if K3b can still be trusted. Your mention of the cheatcode "testcd" is well appreciated, as that test returned a failure on the K3b-burned DVD. I'll run some comparisons of these two burned disks later on to see where the error lies on the K3d disk: The message,"/bin/sh: error while loading shared libraries: /libx32/ libdl.so.2: invalid ELF header" (as shown on my 32bit computer) causes me to suspect the boot sectors of the DVD By the way, I'm downhill from the "Apex" over here in Wilmington.
