[opensuse] Re: uefi on the second disk

Hello,

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 hdd)

any idea?
thanks

Hi
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, are your sure it's not sdb? This may be
your issue if the ssd is sdb, you need to tell the nvram where it is as
it defaults to sda.

So assuming it is infact sda and no efi entry for openSUSE, then;

efibootmgr -c -L "opensuse-secureboot" -l "\\EFI\\opensuse\shim.efi"

If it's sdb, then you need to use -d /dev/sdb in the above as an option.
