I've just gone back in again, and I see that. Of course, I am still VERY confused at how this

can boot, and nobody seems to have any answers, and I'm sure not smart enough to have pulled off any magic, but at least it isn't the /boot that I [am pretty sure I] saw in other passes.
It is not /boot, it is BIOS BOOT partition. Differences: /boot is formatted. BIOS BOOT is not formatted /boot is mounted BIOS BOOT is not mounted /boot is hundreds of MB BIOS BOOT is just 8 meg. BIOS BOOT partition is simply a bit of code that GRUB needs to boot the computer at early stage, on GPT disks. On traditionally partitioned disks, grub used code written starting on second sector of the disk, till the first partition. By accident of design there was always some free space there. On GPT disks there is no such space, but there are hundreds of partitions, so one is used to place the same code. So, I repeat: to boot a GPT disk in BIOS or BIOS Legacy mode, without using UEFI, you *need* that partition. Don't meddle with it. Let YaST install it. You do not need that partition IF you mark one partition as bootable, and put sysboot in the MBR. Still, YaST will insist on creating that partition, so let it do it. It is just 8 meg, and you will need it in the future. DennisG also explained that partition two days ago. Ah! Windows can not do this, AFAIK. -- Cheers / Saludos, Carlos E. R.
