    Question "BIOS Boot partition missing" problem

    Hello,
    Yesterday night my syste crashed, so I had have to build system again. I made all partitions (reconfured them), but, when I opened listi of partitions i Partitioner it says:
    The system might not be able to boot:


    • A partition of type BIOS Boot Partition is needed to install the bootloader.
    • Such a setup is not supported and may cause problems with the bootloader now or in the future.

    Do you want to continue?
    I continued, ofcourse, system works, but what is that partition that missing, can i creater it and how?

    This is what I got, if I list pertitions:

    Code:
    zlatic@dhcppc2:~> lsblk
    NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
    sda      8:0    0 223.6G  0 disk 
    ├─sda1   8:1    0   500M  0 part /boot/efi
    ├─sda2   8:2    0  20.1G  0 part [SWAP]
    ├─sda3   8:3    0    60G  0 part /root
    └─sda4   8:4    0   143G  0 part /home
    sdb      8:16   1  14.4G  0 disk 
    ├─sdb1   8:17   1   4.1M  0 part 
    └─sdb2   8:18   1 133.8M  0 part

    Maybe show (as root)
    Code:
    fdisk -l
    so we can see what the type of the partitions is.

    “lsblk --fs” is the current preferred method to display partitions.
    Code:
    NAME   FSTYPE LABEL       UUID                                 FSAVAIL FSUSE% MOUNTPOINT
    sda                                                                           
    ├─sda1 vfat               ????-????                             492,2M     2% /boot/efi
    For the OP, “/boot/efi” – 500M – “sda1” – is OK …
    • Only need to check if, the filesystem type is “vfat” …
    • And, the free space …

    @Vajcek:

    In the UEFI BIOS, does the boot point to an openSUSE EFI key?

    During the boot, before the openSUSE “choice” splash, was there a blue screen asking to verify that the (openSUSE) EFI key is OK to use?

    If it is working, then no worries.

    You have a partition "/boot/efi". This suggests that your system can use UEFI for booting.

    The installer complained about a BIOS boot partition. This suggests that your system is not actually using UEFI.

    That's you real underlying problem. Is it, or is it not UEFI?

    What most likely happened, is that you booted the installer in non-UEFI mode, so it went with "not UEFI".

    It is possible to load OS installer with legacy BIOS mode and install OS for UEFI mode.
    Installer will complain, simply be regardless of it.

    Maybe preferred by you. I tried to find how to get the partition type with lsblk, but failed. It is also not in your example. Thus I still prefer fdisk -l which shows it without much fuss:
    Code:
    boven:~ # fdisk -l
    Disk /dev/sda: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors

    Units: sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 4096 bytes
    I/O size (minimum/optimal): 4096 bytes / 4096 bytes
    Disklabel type: gpt

    Hi
    Maybe PMBR ~8MB partition, @OP can you show the output of;

    Code:
    gdisk -l /dev/sda
    parted -l

    Sorry, I did not be able to post for couple of days, since this is the only way to contact you. Computer that I posted Thread from is not in function. So, this what I write is from reformatted computer, repartitioned SSD. This is answer your question:

    Code:
    Device         Start       End   Sectors  Size Type
    /dev/sda1       2048   1050623   1048576  512M EFI System
    /dev/sda2    1050624  42993663  41943040   20G Linux swap
    /dev/sda3   42993664 168947711 125954048 60.1G Linux filesystem
    /dev/sda4  168947712 468862094 299914383  143G Linux filesystem
    I will now also repliy to everyone in this Thread who asked me to reply. Also, I will teach from your answers, because I know what I know also by your answers. Thank you for answering my questions.
