EFI issue in openSUSE 15.2


I am one of those filthy multibooters. I installed openSUSE 15.2 Leap, mostly for the purpose of reviewing it for my podcast, Distrohoppers' Digest. I got it completely installed... except for it reported that it couldn't find an EFI partition of at least 550 Mb. This is odd, since my EFI partition is over 2 Gb. But so it went. I have a fully installed version of openSUSE and I can't boot to it.

The question is, how do I get openSUSE to recognize my EFI partition and write boot?

I looked at efibootmgr and it does not look full, nor does it have any ghosts of old EFI boots jammed in there.

It's all a learning experience. Please help me learn.

I suggest to pastebin output from bootinfoscript and provide the resulting URL so people here can look for clues to your failure.

I have lots of multiboot PCs, 3 of which are using GPT/UEFI, and FAT32 ESP partitions of 320MB. All UEFI of mine are booting from openSUSE Tumbleweed's Grub, which is configured with a custom.cfg that boots Leaps, Fedoras, Debians, *buntus, Mageias & Mints.

Manjaro's bootloader might not be recognizing an openSUSE BTRFS / partition. If so, the only fixes I'm aware of are reinstalling 15.2 using EXT4 instead of BTRFS, configuring 15.2's bootloader to be in control, or choosing some other bootloader that does support BTRFS to be in control, but it may be that Manjaro's Grub simply needs to be updated to load a BTRFS module. I don't ever use BTRFS or Manjaro, so can't readily check.

Wanting a 550 MB ESP sounds wrong. Are you sure it wasn't 500MB, which I have seen others report as a required or installed size? What size is it? If the disk is more than 16TB and using 4k sectors without 512b sector emulation, the minimum ESP size per UEFI specification is 260MB. openSUSE doesn't actually require an ESP partition of more than 100MB, but it does complain when it isn't 500MB. When the complaint appears, simply ignore it and proceed anyway.

That is a message that one usually gets if the efi partition isn't mounted to /boot/efi. At the partitioning stage did you select the efi partition to be mounted at /boot/efi? If you did I would think it would be listed in your fstab.

I did everything I know to do to point the boot at the EFI sector. And I've been doing this for a long time.

Answer to the previous person: I only know it stated a minimum 550 Mb. And no, it's not Manjaro interfering -- SUSE refused to write the boot, said so, and then didn't. But it went right ahead and installed anyhow. I could probably use SuperBoot2 to get into it, but haven't tried yet.

As a multibooter, I know about designating certain partitions in certain ways. I attempted to click on the EFI partition and designate it as the boot sector, just as I had designated sda3 as the openSUSE installation, but kept getting told it did not have at least 550 Mb space (which it clearly does). It came up twice again in the installation, and did not accept my input.

At this point I'd like to know how I can fix it, not identify what went wrong during installation.

Provide the information I asked for and someone should be able to recommend a repair procedure.

What do you mean by this? I read it as you set it to mount at /boot

Considering I can't boot into openSUSE at all, again not having tried SuperGrub2 or the like, how am I to get any output?

You said something about multibooting, so I assumed you had more than one distro on this system. Boot the installation media, mount the partitions at /mnt, mount each of the directories /dev /proc /sys to the same directories of your root partition with --bind option, choot and run grub2-install and grub2-mkconfig

Last night I reinstalled. I had wanted to install openSUSE on sda3, and it wanted to install on sda5. I think whatever I messed up last time was trying to make it go to sda3, although I've done that in a lot of other installers without incident. Anyhow, this time I decided to let it install where it wanted to, and it all went.... almost well, or well enough at any rate. I had to then reinstall Bodhi, which is what had been residing on sda5, but in so doing I seem to have gotten rid of more than a few papercuts I had with that distro.

But openSUSE is booting from Secure Boot, and my other distros are not. So my GRUB menu only features my non-SUSE distros. I *can* boot to openSUSE, but to do so I have to get into the BIOS boot menu (in the case of my System76 Kudu 3 laptop, that means holding down F7 at boot time). I don't have a problem with this, although it is a small amount more complex than I'm used to. At least they all boot now.
