I’m trying to boot openSUSE 13.2 RC1 KDE Live from an usb stick. I downloaded the ISO, both the md5sum and SHA1sum match. But when I try to boot from stick and select “check installation media” or similar it reports before booting “check: md5sum wrong” and after a while the boot just hangs. What can I do? boot.log, kdm.log & Xorg.0.log here: http://paste.opensuse.org/47427944
I made the live usb by removing the existing partitions with Gparted, started SUSE Studio Image Writer and selected the ISO. It gave no visible error messages. I’ve tried writing many times using 2 different usb sticks with same results. I can mount and view the files without a problem. I’ve tried also doing the live usb using “dd bs=4M if=[ISO-file] of=/dev/sdf” with same results.
I’ve downloaded the ISO couple of times more and tried them with same results. I tried with 13.2 DVD, selected “check installation media” or similar and it says “this is not suse installation media”. I can run installation process all the way to finish but again it won’t boot. I’ve tried with . Burning to DVD has never be successful for me and this time was no exception (fails during boot).
I verified the md5sum and SHA1sum from command line using “md5sum|sha1sum [ISOfile]” I’ve have installed 12.3 and 13.1 several times to same machine using same methods afaik without problems but I don’t know if this really is 13.2 related.
Check media only works on CD/DVDs on USB devices it will always say it is wrong becuae the way a USB device is organized. Test the ISO check sums if correct then the USB image if copied correctly will be ok also. The correct way is to do a binary copy of the iso to a device (NOT a partition on a device) and never us any special Linux boot helpers they are not needed the iso is ready to boot as is.

You can not verify media if it is “burned” to USB. It only works right
with CD/DVD.
So do not run that check, just run the live or install it⁽¹⁾.
You can, and should, verify the downloaded image on the hard disk.
(1) It might be possible to check manually with a concoction to tell
cmp to compare the exact number of bytes. I have not tried, and must be
done before the first time you boot it, because then it is modified.

Not only not needed, most of them break booting.
Often people try the methods used on other distributions, which fail,
and only then they ask here. They did not read opensuse.org instructions.

I just removed existing partitions with Gparted, didn’t make new ones and used SUSE Studio Image Writer to write the iso. And when that didn’t work tried the same with dd. If I don’t choose “check installation media”, it still won’t boot. Should I make a bug report about this? Are there other log-files or information I should include? In boot there was a line about “bug: kernel can’t handle paging request” or similar but I can’t see it in those log files.
Don’t know if it’s related but if I install kernel 3.14.0 or higher in 13.1 it gives a kernel panic at boot. 3.13.7 or any lower boot fine. Using repo Kernel:/stable/standard/
I have downloaded the live kde to a usb, however when i go to open the file Roxio opens and wants to burn/save onto dvd/cd. i thought the idea was just to have on usb?
Roxio is CD/DVD burning software ergo it want to burn a CD/DVD
Apparently on your machine and ISO file is associated with Roxio so an attempt to open it in a GUI will start Roxio.
It is also Windows so if this is Windows 8 it has been reported the Imagewriter may not work so here is another one that should work on Windows 8.x
Are you saying that openSUSE won’t boot in live mode from your USB stick? Or are you simply saying that the “check installation media” test fails? I can’t tell for sure from what you’ve written.
How big is the USB stick you’re putting the image on and running it from?
About openSUSE, installed to a USB key: It (i.e. ImageWriter, or using “dd”) creates a partition on the USB key that looks to the computer, for all intents and purposes, like an ISO image. That’s where the boot info and compressed file system are, just as if you’d written it to an optical disc. (And that’s probably why Roxio is starting up on your computer when you plug in the USB key when running Windows.)
With the remaining space on the USB key, it creates an ext3 partition, which it uses to store your changes, using overlayfs. It acts as persistent storage, as if it were running from a real read/write hard drive.
Naturally, if you use a small USB key (say 1GB), this doesn’t leave much room for the overlay file system, and it will complain about not having enough available disk space, and stop working. You can turn off the use of the persistence feature through a boot-time parameter, if this is your issue. That parameter is “kiwi_hybridpersistent=no”.
I’ve got two kinds of error messages during boot although they don’t appear in boot.log: “BUG: unable to handle kernel NULL pointer deferences at 0000…” and “Unable to handle kernel paging request…”. Pics:http://tinypic.com/r/34pcpx1/8http://tinypic.com/r/2ue2q0g/8 Is there some way to log all the messages during boot including those? When system hangs it isn’t hard locked so I can reboot by SysRq+B for example. I filed a bug report: http://bugzilla.opensuse.org/show_bug.cgi?id=901550

Report that in Bugzilla, please.

By serial port (232) or network to another machine.
