dear Tracey,
i just re-installed Manjaro again.
It uses the same Calamares installer as Solus.
Because Solus was installed falsely as GPT on the HDD one hour ago, the similiar Solus-installation-pic from before now said BIOS + GPT.

But even though the Manjaro-installer recognised it as GPT: the Manjaro-installer created a MSDOS - Partition Table on the Master Boot Record.

All this in the summary and during installation.
my laptop is now bootable with Manjaro and its Grub, and all works.
it seems the Manjaro-installer is more correct in choosing the format of the partition table (MSDOS or GPT), while the Solus-installer seems to always choose GPT.

...and i still have no idea how i could install Solus successfully.

deaar @Buzz and dear @blueicetwice,
i tried this Rescatux and i can NOT RECOMMEND it !!!
i am afraid it is even MALWARE!
i pressed the "restore grub" button. it did something. ended with an error.

afterwards i tried to boot with both Solus and Manjaro installation sticks: NO WIFI NETWORK BLUETOOTH possible anymore.
everything gone.
i had to dismantle my laptop and remove the BIOS battery for 20 minutes in order to get everything working again.
i dont know what this Rescatux did, but it seems to be evil!

i can only hope that i dont have any MALWARE on my Master Boot Record now, after using this.

    "deaar @Buzz and dear @blueicetwice,

    Nein, das ist nicht richtig !!! It is nicht Malware but rather Palware...

    I have used if for at least ein decade. It even helf me in my first divorce. :-))

    Your installation should be on the target drive, however, there will be no boot
    order in the MBR. Try it again, BTO, and select another option, as the first may
    not work. Rescatux, at times, needs a second try, in order to be successful.

    The last time, it placed all the five OSs on the bootloader. It also changed one
    of my three HDDs to a
    GPT partition. Yes, four Linux and MicroToylets.

    A good read on GPT partitions.

    BTO I am sorry to hear about your bad experience with rescatux, it is a respected tool that has been helping people with similar issues to yours for many years now. It is a shame that you did not persevere with it's features as there is a wizard feature that can attempt to diagnose the problem and rebuild grub from scratch.
    While tinkering with old bios run PCs it is very easy to corrupt or delete the grub loader and Rescatux has always diagnosed and fixed my problem.
    I do not understand how anything that happens on your hard drive can affect the behaviour of a live environment, a computer will happily boot into a live environment with no hard drive installed. The issue you have here is looking much more like hardware issues.

    Did you try actually following my instructions?

    My instructions don't care which version of GRUB is installed where. It overwrites everything on the first 16 MiB of the disk in your laptop, ensuring you have a clean slate as far as bootloaders go.

      Try to select Manual partitioning -> New partition table -> Select MDR -> Create partition / (if you want /home separately) and continue accordingly installer commands. When it informs about GPT, click ok and next.

      dear ermo,
      thanks for your support!
      why did i not follow your instructions?

      1. someone in the Manjaro-Forum wrote that its not good to just erase the master boot record. there always should remain a partition table + bootloader to not damage the whole disk. so it is advised to better overwrite the contents with new info than delete them.

      2. today 2 tries to install Solus, but again the Solus-installer always only created a GPT Partition Table on the Master Boot Record. I assume this is the reason why my laptop is unbootable from that.

      3. re-installed Manjaro and the Manjaro-installer creates a MSDOS Partition Table on the Master Boot Record and MBR-bootloader. from there Manjaro boots into a GRUB without problem.

      4. As the Solus installer only creates GPT partition table on my MBR master boot record, my conclusion was that it would have made no difference if i had followed your instructions to erase the master boot record or not, because the system ends up unbootable in any case, wheter i had erased the MBR before or not.

      the Manjaro-installer delivers MSDOS partition table out of the box.
      if you have any more ideas what i could try...

        BTO someone in the Manjaro-Forum wrote that its not good to just erase the master boot record. there always should remain a partition table + bootloader to not damage the whole disk

        That is in the case that the user don't want to delete the mbr partition for "reuse" in later installations.
        I recommend, if doing a clean install of solus, to not conserve any partitions and letting the installer to do what it needs to do, or for the advanced user, make manual partitioning.
        Just take into account Manjaro is not Solus, Solus is independent and implements some things different compared to other distros; one example is that solus uses clr-boot-manager to manage boot in uefi or bios environments and not directly in to grub.

        I have pondered this I believe I would do what Ermo asked alot of stuff can hide in a MBR and if you
        wipe it there is no reference to manjaro or anything and no MBR at all.(So solus will install a fresh Boot)
        I had to do this years ago wipe a disk to correct things. (More than once)

        Also on a note from what Nolan mentioned it appears your laptop will do eufi from what I can tell to.

        Either of these two things I would think would get Solus going.

        Note: Rescatux has been around long long time even used it back in the day and prob if it had issues correcting
        things I would do above mentioned.

        And when you say Solus wont boot is there anything on the screen?

        Maybe your USB drive has a corrupt installation. As advised above, try Ventoy.

        BTO, my rig remodeled in 2011, it did the same thing, placing a GPT on one of the HDD. The MBR, is out-of-order and needs to be repaired. Reinstalling Solus, will not solve this issue, IMHO.

          in that case, it's interesting 🤔
          EDIT:
          GPT partition table is for UEFI systems
          MSDOS partition table is for legacy BIOS, GPT won't work here rendering the ssd/hdd un-bootable as a direct consequence.

            pomon, excellent guide indeed.

            This command will indict weather one is using a legacy or UEFI boot.

            ls -d /sys/firmware/efi

              1. PLEASE do NOT highjack/spam my request !!!

              2. PLEASE: it is NOT a question of wheter i have UEFI or BIOS !

              i AM definitley on BIOS on this machine.
              and i have an even older laptop that ONLY has BIOS too.
              and i want to keep them aline.
              but if i can not get it to work here, then it does not work on the older one too !!!

              blueicetwice This command will indict weather one is using a legacy or UEFI boot.

              I think you might have meant that it will indicate whether ... legacy or UEFI.
              That doesn't seem to be something that's worth an indictment, whatever the result of the test.

              I don't really see the point in trying to help you if you refuse to do the steps exactly as I laid them out.

              There was a reason I laid them out that way and part of that reason was that, this way, the solus installer and boot manager could do exactly what they need to do from a clean slate.

              But if you don't want to do that and instead want to insist on following Manjaro advice when you're trying to install Solus and asking for help on accomplishing this on the Solus forum, well, I guess there's no getting through to you.

              Best of luck I guess -- I'm officially out of this conversation.

              • BTO replied to this.

                @BTO I would strongly recommend following the advice ermo provided. He's part of the Solus Team, helps with package and system development and has helped test our ISOs including multiple ways of installing.
