On a laptop I have windows (8, then 8.1, then 10) and several
openSUSE (right now two leaps and one tw)

this laptop have two disks, one of them being a 24Gb internal ssd.
Being much faster than the HDD, my main Leap is on it.

But I can't make the laptop read the efi partition of the ssd.

Is it possible to trick Yast (or grub-install) to write the efi
boot file on the hdd (/dev/sda1)?

I tested all what I was thinking of, with no result, I even copied
the /boot/efi/EFI files to the same folder in the hdd (named open),
but the bios don't see them

right now I boot from a grub menu from the other Leap install (on

any idea?
No need to trick anything, just tell the nvram via efibootmgr where
the efi file is.... assuming sda1 set to gpt, has a small partition <
500MB, formatted as fat and set to type ef00?

Just boot from a rescue USB (via the system boot menu), then run;

efibootmgr -v

Where does the existing openSUSE boot from, or even exist?

By default efibootmgr uses sda,

No, it does not. efibootmgr has no defaults and grub-install by default
is using whatever is mounted as /boot/efi.

I'm not referring to a mount point, or grub-install. My
reference is to efibootmgr and the nvram entry which identifies the disk
which has the /boot/efi partiton. I can have multiple disks,
multiple /boot/efi partitions, I just need to add an entry for which
one I wish to have available to boot from. In those cases I need to use
the -d flag...
