But now I used ext 4 for the root partition but after the installation I get the message that no boot device can be found. But actually I made an extra uefi boot partition which is unencrypted. Here is also a screenshot I did from the configuration when installing the system. I also tried with deleting the second /boot partition but didn’t help.
There was a bug that I ran into when testing 13.1 at a pre-release stage. I’m not sure of the bug number. It was said to be fixed, but I had no sure way of testing.
What happened, was that after the install I found that “/boot” was empty (except for the “lost+found” directory). What was supposed to be in the “/boot” partition was actually in the “/boot” directory on the root partition and hidden under the mounted “/boot”. I “fixed” it by copying that to the proper “/boot” partition. I’m not sure if I had to also manually re-install grub.
As I recall, this apparently happened because my root partition had previously been formatted as “btrfs”, and I had specified reformatting as “ext4” during the install. Apparently that confused the installer.
I’m not sure if that is what you are seeing. You did not provide enough detail.
Did you check the timestamp (i.e. date) of the files in that opensuse partition? That’s usually the date of install or most recent update. It should tell you whether they come from your recent install or were a left-over from an earlier install.
I have to say that I found no solution so I made a backup of my home directory and did an fresh installation.
Before I tried to reuse the lvm partitions and I formated the /boot and /boot/efi so the files there should have been fresh?
The only thing that I can think about is that whenever I install openSUSE I get a new boot entry in the UEFI/Bios. And I do have to start it through this entry. When I select the right hdd it does not work and I get the error that no OS has been found.
I found out about this because I also use Debian 9 and there I have also to select the Debian entry in the boot menue.
So maybe this hasn’t been updated?
Thank you for your reply. No I’m using an Gigabyte Z77X-UD3H Mainboard which was built around 2012. I guess somewhere at this time was the switch between classic bios and the new UEFI. So this is a mainboard comes with both. I can use UEFI and legacy mode bios.
I got the information from this forum that I have to boot the installation disk from the drive with uefi in front of the boot menue. When I do a new installation I always remove all other hdd I don’t need. I have 4 of them: 1 for Debian, 1 for windows, 1 ssd for suse and 1 hdd for the home partition of suse (ssd is only 80gb). so each operating system has it’s own bootloader and uefi partition. Sometimes you have the problem that the operating system writes the bootloader automatically to sda (the first hdd in the system) which can also cause trouble.
It kind of more work when I have to do a fresh installation with new lvm setup because I have to backup the whole lvm/home which get formatted during the process.
