@Tratkazir_the_1st You can make a Debian install disc or USB stick, and enter into its built-in rescue mode to chroot into OpenSUSE's filesystem. If a spare partition is available in at least 1 MB of size, you can then use yabootconfig -b /dev/sda(x) to install a rudimentary bootloader into said partition, depending on its hierarchical position in the partition map.
That said, I don't have any experience with OpenSUSE and have no idea if this will work, but perhaps it is worth a shot at least as far as bootloaders go.
(For God's sake, anybody, please correct my spelling, I feel it IS awful 😀 ).
So, the battle continues. I have installed SUBJ to a SAS drive (It's identified as disk@5 in OF, with GPT partitioning. - BTW, is there any way to check the partition map within OF? 🙂 ). But, as expected, there is no boot loader that OF can read. Only the first partition which I formatted as HFS, and labeled "Apple_boot", with partition type 50 in the GPT fdisk tool. I am attaching a picture.
Obviously, disk@8:3 is macOS Leopard. So, is there any way to install some boot loader to a partition visible to OF & try to boot from there? (GRUB installed from Gentoo detected the OpenSUSE installation, but it's unbootable, as it can't find the partition's UUID.)
I have corrected your spelling, punctuation, sentence structuring, and terminology where applicable while preserving its (perhaps questionable) grammar or flow to the best of my ability.
Taking several presumptive liberties here, there is generally no strict standard of conversational speech to closely adhere to while writing in the English language (or any other language, sans programming), as everyone has their own subtly distinct style of tone, sentence structuring, and vocabulary, much like while talking in real life (or rather, physical reality - it can be argued with great plausibility that "real life" is now a functional secondary to the Internet, contrary to 10 or 15 years ago, making one question which of them the actual "real life" is).
The point of course is that everyone has their own slightly different standard of communication that is effectively their own personal spin on the subject language, provided that they can indeed read and write in said base language.
Going further ... this established point can be interpreted as relevant to the original subject matter of questionable writing in a variety of ways, depending on the individual's perspective and scenario context...
