I can’t boot Suse Live CD (KDE, 32bit)afsfafasfI can’t boot Open SUSE 12.3 Live CD (KDE, 32 bit).
However, I have no problems booting other DVDs/CDs, such as:
Fedora 14, 32 bit
Ubuntu 10.10 32 bit
Ubunto 11.04 32 bit
Lubuntu 11.04 32 bit
etc.
I just tested this to make sure. It is not a configuration issue. These are DVDs/CDs I tested after the SUSE 12.3 problem happened.
Is there a known issue with the Open SUSE 12.3 live CD on older PC’s?
My PC is around 3 years old and boots basically anything - except SUSE 12.3 it seems.
The error message from the Bios is: ‘cannot find boot device. Insert valid boot medium.’
The PC does not seem to find anything to boot on the Live CD.

your subject line say “CD does not boot”, are you now saying you
burned the iso to a DVD?
I get that on one of my computers. It’s a failing CD reader device.
In my case, it will boot a DVD but it won’t boot a CD. You seem to have the reverse problem.
It’s an older computer that won’t boot from USB. However, using PLOP boot manager (google around to find it) I am able to boot USBs, so I avoid the CD/DVD device if possible.
We are like computers. We read what you wrote, not what you thought you wrote. And of course when you think that it will help you, when you tell us things that are not possible at all and at the same time assume that we then will guess what you did correctly, you are wrong.
Now please tell us how, with which tool and with which methods you did burn that DVD. The ISO should be burned as an image, not as a file. And also if, before trying to burn it, you checked the downloaded ISO using one of the methods described on the download pages.
I’ve already succesfully burnt and used 30 or so Linux ISO images to DVD/CD over a period of more than 8 years, and I’ve used SuSe Linux in the 90’s, so I’m not a newbie.
I’ve checked the MD5Sum for the ISO image and it is equal to what is mentioned on the site for this ISO image.
Brasero (on Ubuntu Studio) did not want to burn the ISO image (it got stuck twice at the end while burning the DVD), therefore I needed to start Windows (for the first time in months on this computer) and use Nero to open the ISO file (‘as ISO file’) and burn it to DVD.
I can open the downloaded ISO image with ‘archive mounter’ and ‘archive manager’ on Ubuntu studio.
I’ve tested some more. The DVD does not boot on three computers, one of them less than two years old. None of them support Unified Extensible Firmware Interface (UEFI) though.
I am also very suspcious of the installation media. Are you by chance using an RW instead of a +R or -R (apologies, but the question needs to be asked). RW’s are notorious for working wonderfully for a large % of the time, leading one to a false sense of their infallibility, and then inexplicably causing errors one day, but because of past good behaviour one does not suspect the RW.
Another thought …
The GNU/Linux versions you quote are very old. How long ago was it that you burned them ? Could it be your burner is starting to fail ? I burn a massive number of DVDs, and its rare I can have a burner last more than 3 years before I need to replace it.
wrt the GNU/Linux distributions you quoted I note:
Fedora-14 has the very old 2.6.35.6 kernel.
Unbuntu-10.10 has the very old 2.6.35 kernel
Unbuntu 11.04 has the very old 2.6.38 kernel
There have been massive changes to the GNU/Linux kernel wrt graphics since those GNU/Linux kernel versions. Have you tested on a new kernel with any other distro ?
Can you tell us what graphic hardware was in the PC’s that you tested on ?
Did you try any boot OTHER than the nominal boot ? ie did you try ‘NoKMS’ from the boot menu ?
Well, to answer your questions, I burnt another copy using another brand of DVD, same result, it won’t boot.
After all this, I also burnt two copies of other distributions (which I downloaded earlier to test my DVD writer), and both DVDs booted just fine.
Because of the above two tests, I think that it is unlikely that the DVD burner is faulty and it is unlikely that both SUSE live DVDs are faulty.
I lack the time to pursue this further and it is not a matter of life and death. I just wanted to test SUSE 32bit Live KDE. I’ll probably try the 64bit edition in a few weeks and see how it goes.
I can burn other Linux live ISO images, and all boot just fine.
As I mentioned earlier, the ISO image of SUSE has the correct MD5 checksum.
I don’t have time to pursue this further.
Thanks for your help.
IMHO there is a problem with the ISO file, I basically tested everything on my end.
Just FYI.
I’ve burnt both 32 and 64 bit Live KDE to DVD and booted and installed from them without any hasle. No difference compared to using the same ISOs from a USB device.
If its a problem with a kernel version you will also likely encounter similar on other GNU/Linux distributions that have a newer kernel version than the one’s you quoted. And IMHO in such a case trying a 64-bit openSUSE version will make no difference. I fail to see the logic there.
There could be other reasons than the newer kernel version for the failure, such as specific wrt PC hardware (graphics/bios acpi implementations of newer compared to older, etc … wrt specific to updated libraries ) but with the definite dearth of information given and with questions asked in the thread not answered, it is impossible to tell.
If and when you have the time/energy to provide more information, I suspect it will be possible to sort this.
