    @ mr_raider ... oh, now, I wonder what you are up to, sneaky fellow !!!

    Of course, we all can get almost anything working, and we have here, but, many Internet articles will certainly caution you about this UEFI thing and dual booting and ESPECIALLY about dual booting with Windows. One I like to read is AdamW:

    Recommendations

    The following are AdamW’s General Recommendations On Managing System Boot, offered with absolutely no guarantees of accuracy, purity or safety.

    If you can possibly manage it, have one OS per computer. If you need more than one OS, buy more computers ... Everything will be nice and easy and work. You will whistle as you work, and be kind to children and small animals. All will be sweetness and light. Really, do this.

    If you absolutely must have more than one OS per computer, at least have one OS per disk ...

    If you absolutely insist on having more than one OS per disk, understand everything written on this page, understand that you are making your life much more painful than it needs to be, lay in good stocks of painkillers and gin, and don’t go yelling at your OS vendor, whatever breaks. Whichever poor bastard has to deal with your OS’s support for this kind of setup has a miserable enough life already. And for the love of cookies, don’t mix UEFI-native and BIOS-compatible OS installations, you have enough pain to deal with already ...
    and so on, like that.

          Now you got me curious!

          Could someone tell me what these suspicions are about?

            @mr_raider
            Here is the output:
            for your information:

            you tried to install linux at least once in MBR mode. I don't even want to know how the installer allowed that to happen, since installing in legacy mode to a GPT drive requires what's called a "bios_grub" partition. My guess is that the installer said eff it and tried to shoehorn grub into the first 1MB of your drive with no warning. That's damn near close to assault if you ask me.

            What you need to know: if you ever allow your PC to boot in legacy mode, it will find that half aborted fragment of grub and throw an error. I suggest you go into your firmware, and fully disable any possibility of legacy mode. Enable UEFI only. Disable legacy or CSM completely.

            If the day comes when you need to wipe that drive completely, we will show you how to nuke that piece of grub.

              Ha! mr_raider addressed that above: basically, somehow, in the older traditional MBR space (on your drive), you installed some older GRUG legacy code, which is not what you want or need for your setup. Not to worry, though, that code, in the first 512 bytes, will just sit there, idle, harmless, and not cause any problems (unless, in the unlikely event, you, as mr_raider pointed out, somehow allow your computer to boot in the older BIOS legacy mode). As he says, if you ever re-do your entire disk or something, he/we can show you how to clear out that old MBR garbage. (Many people probably have junk like this laying around their disks, either at the beginning of a disk or at the very end -- not to worry, though.)

              @Qqmike
              Thank you for the links, I will look at it.
              I wouldn't. Seriously, though, that article is more for advanced interest in UEFI, for people like myself or mr_raider or Vinny! I would not get too wrapped up in the Zen of UEFI, UNLESS, of course, you do wish to make it kind of a specialized side interest/hobby of yours. I would stick to general Wikipedia articles, or post your issues here, or refer to the expert on EFI, Rod Smith, like this page (and he has dozens of specialty pages covering almost every EFI issue):

                  Ok, thanks a lot for these explanations. I would lie if I said I understood everything, but I will put my firmware (is it how this should be called?) in UEFI mode only.

                  Concerning the smileys I have the same issue.

                    I suggest it's a browser issue. I don't have that problem when here on my Apple iPad (Safari), nor do I experience it when on my Kubuntu VM's (Firefox).

                        Hmm. Well, something else is affecting the smilies then. Plugin(s) maybe?

                              (Another problem posting, has happened almost everytime I post lately: I press the submit or post button, and after a pause I get this message:
                              The following errors occurred with your submission
                              This forum requires that you wait 30 seconds between posts. Please try again in 28 [or some other integer less than 30] seconds.
                              BUT, then I open a new instance of Kubuntu forums (in a new tab), and I see my post did post, even though that error message implied that my post was being held up and I was to try again in x seconds. If I do wait the x seconds and try to post again, it may very well post, in which case I will then see two posts, each a duplicate of the other.)
