Another question answered: yes, it has to be the primary disk. I installed a |
| 8 |
small test system on another disk. It has its own FAT-32 /boot partition, in |
| 9 |
which I set up a similar directory structure to the main system's. Efibootmgr |
| 10 |
still insisted on adding the UEFI entry to the main set, in spite of my |
| 11 |
telling it to use the secondary disk. And the BIOS couldn't see the image on |
| 12 |
the secondary disk. |

The conclusion is that, at least on this motherboard, there is precisely one |
| 15 |
set of UEFI boot images, and it lives on the primary disk of the system. Well, |
| 16 |
I haven't yet worked out how much of it is on the disk and how much in BIOS |
| 17 |
storage. The point remains, however, that I can't spread boot images over |
| 18 |
several disks. |
