ISOs burned with K3b are not readable or bootable

Asked by Seth B on 2009-03-23

I have used K3b on Ubuntu installed in Windows as my burning software for a while and have not had any problems, even burning files from the Windows file system. I am redoing my OSes cause I just got a new hard drive, but all the ISOs I have burned will not work. It seems like Windows can read a couple of them, but my computer will not boot them, and Ubuntu will not read or mount them. It either does nothing, or it says it is unmountable. I know it is not the drive because another DVD of OpenSuSe 10.3 works.

Any help is appreciated.

Well, could you be a bit more precise about which iso your problem is? Did you check the md5 sums of the burn? (for more info on md5, check out

Other than that, maybe you are using a DVD that is damaged?

Try another software to burn, Brasero or Gnomebaker. Check md5sum of your iso files. The isos may be corrupted.

Please also to activate the "Verify" of the data and then please also use a lower speed to burn...

Hope this helps
