from Jean-Daniel Dodin
Goal: install Leap from the dvd (in fact usb stick)
I worked a lot, with partial result, explained below, sorry to be a bit long.
The grub-efi 32 bits package is available on Tumbleweed. Why on earth is a
package available with no use at all? I guess that the
grub2-i386-efi-2.02~beta2-55.1.i586.rpm is there for some use.
I could extract the grub.efi (32 bits) from this package.
right now, I can navigate from the grub console (I start with the debian dvd,
32 bits uefi) to the openSUSE Leap dvd, but the hybrid structure is a bit
confusing. I just notice (I forgot that) that the kernel name is simply
"linux", not vmlinuz(s).
I can do this because I have two usb ports, I use debian on one and Leap on the
other.
like this I could start the Leap install, choose defaults and the install went
well.
BUT. It of course didn't boot (64 bits grub.efi). I couldn't start it with the
debian dvd, because Debian do not read btrfs :-(
So I had to build my own usb stick with an EFI partition with openSUSE
Tumbleweed 32 bits grub. On this computer, the partition not only must be FAT32
and flagged type 1 (EFI, GPT), but also must be the first one on the stick,
else it's not seen.
Finally I could start my installed Leap with some sort of:
set root=(hd1,gpt6)/@/
linux (hd1,gpt6)/@/boot/vmlinuz nomodeset
initrd (hd1,gpt6)/@/boot/initrd
boot
don't know what is the /@, it's added automatically by the TAB completion and
the system don't boot if omitted.
from the started Leap, I could copy the 32 bits grub to the Leap install (gpt1)
and register it from Windows 10 with easyuefi.
I still have to automate the boot.
Leap runs pretty well on this machine, with the problem (same on debian) than
the screen is rotated 90�, that is in tablet format, when the keyboard and the
touchpad are connected on the long side, so the screen is left turned, very
unfriendly.
Bur as long as I have to use framebuffer, I don't think there is a X solution
(rotating works with console only).
so it's possible...
