--- Begin Message ---Hi all, hi Thomas esp.,for a school customer we set up a FAI environment recently and stumbled over a phenomenon that might required an adjust in FAI's partitioning tool.We installed an HP notebook via BIOS mode using the partitioning rules given below. After FAI installation was successful, the notebook would not boot into the installed system. The notebook BIOS acted as if there was no system installed on the hard drive / SSD.What fixed the problem was toggling the boot flag (i.e. enabling) on the first partition of the protective MBR (see at the very end of this mail).The below data has been obtained from a VM installation. On the VM, the booting also works without above named bootable flag being set.Is this something, we should amend in FAI's set-storage tool? Mike Our disk config we use is this: ``` disk_config disk1 disklabel:gpt-bios bootable:1 fstabkey:uuid primary /boot/efi 512M vfat rw primary /boot 512M-2G ext4 rw primary - 0- - - disk_config lvm vg vg_system disk1.3 vg_system-root / 2G-4G ext4 errors=remount-ro vg_system-swap_1 swap RAM:150% swap sw vg_system-usr /usr 28G-36G ext4 defaults vg_system-var /var 8G-10G ext4 defaults ``` A resulting partition table for this config is this: ``` root@test-workstation:~# fdisk -l /dev/vda Disk /dev/vda: 64 GiB, 68719476736 bytes, 134217728 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Disk identifier: D35E0D51-44FC-42A5-AA8E-6F6EF5F42837 Device Start End Sectors Size Type /dev/vda1 4096 1052671 1048576 512M EFI System /dev/vda2 1052672 5126858 4074187 1.9G Linux filesystem /dev/vda3 5126859 134215646 129088788 61.6G Linux LVM /dev/vda4 2048 4095 2048 1M BIOS boot Partition table entries are not in disk order. ``` For the same partition table the format.log looks like this: ``` root@test-workstation:~# cat /tmp/fai/format.log Starting setup-storage 2.3 Using config file: /var/lib/fai/config/disk_config/LVM_EDU_ROAMING Executing: wipefs -af /dev/vda4 Executing: wipefs -af /dev/vda1 Executing: wipefs -af /dev/vda2 Executing: vgchange -a y vg_system Executing: wipefs -a /dev/vg_system/swap_1 Executing: lvremove -f /dev/vg_system/swap_1 Executing: vgchange -a y vg_system Executing: wipefs -a /dev/vg_system/var Executing: lvremove -f /dev/vg_system/var Executing: vgchange -a y vg_system Executing: wipefs -a /dev/vg_system/home Executing: lvremove -f /dev/vg_system/home Executing: vgchange -a y vg_system Executing: wipefs -a /dev/vg_system/usr Executing: lvremove -f /dev/vg_system/usr Executing: vgchange -a y vg_system Executing: wipefs -a /dev/vg_system/root Executing: lvremove -f /dev/vg_system/root Executing: vgchange -a n vg_system Executing: vgremove vg_system Executing: pvremove /dev/vda3 Executing: wipefs -af /dev/vda3 Executing: wipefs -af /dev/vda3 Executing: parted -s /dev/vda mklabel gpt Executing: parted -s /dev/vda mkpart primary "fat32" 2097152B 538968063B Executing: parted -s /dev/vda set 1 boot on Executing: parted -s /dev/vda mkpart primary "ext3" 538968064B 2624951807B Executing: parted -s /dev/vda mkpart primary "" 2624951808B 68718411263B Executing: parted -s /dev/vda mkpart primary "" 1048576B 2097151B Executing: parted -s /dev/vda set 4 bios_grub on Executing: mkfs.vfat /dev/vda1 Executing: mkfs.ext4 /dev/vda2 Executing: parted -s /dev/vda set 3 lvm on Executing: parted /dev/vda set 1 boot on Executing: pvcreate -ff -y /dev/vda3 Executing: vgcreate vg_system /dev/vda3 Executing: vgchange -a y vg_system Executing: lvcreate --yes -n root -L 2615.39721762767 vg_system Executing: mkfs.ext4 /dev/vg_system/root Executing: lvcreate --yes -n swap_1 -L 2973.955078125 vg_system Executing: mkswap /dev/vg_system/swap_1 Executing: lvcreate --yes -n usr -L 30941.5888705107 vg_system Executing: mkfs.ext4 /dev/vg_system/usr Executing: lvcreate --yes -n var -L 10807.3972176276 vg_system Executing: mkfs.ext4 /dev/vg_system/var Executing: lvcreate --yes -n home -L 15062.9800340777 vg_system Executing: mkfs.ext4 /dev/vg_system/home /dev/vda2 UUID=3463e974-58a5-4195-97b3-91a63c348ca3 /dev/vda1 UUID=B803-DF11 /dev/vg_system/home UUID=67fe2d5a-06cf-4bb1-bded-59fcab454e95 /dev/vg_system/var UUID=476eca23-14c3-49d9-9a98-b32d2dc068f6 /dev/vg_system/swap_1 UUID=3af7d13f-6b7f-4676-afc0-24273ad45477 /dev/vg_system/root UUID=40eb465f-0de1-400f-8fe1-59506e5f563d /dev/vg_system/usr UUID=14d51891-168e-4227-a925-6def80496da4 ``` This fixes the boot problem with GPT-BIOS partition table and the HP notebook: ``` root@test-workstation:~# fdisk /dev/vda Welcome to fdisk (util-linux 2.36.1).
