[SOLVED] cannot select boot device (mga6-sta2)

[magfan]

I have a workstation with two "disks":

/dev/sda is a hardware RAID 10 where mga5 is installed (not UEFI) and from where I can boot. This drive is detected as boot device in the BIOS.

/dev/nvme0n1 is a NVMe PCIe disk where I installed mga6-sta2 (not UEFI). I cannot boot from this disk because it is not detected as boot device in the BIOS. Therefore, I placed a small boot partition for "/boot" on /dev/sda (dev/sda7).

The installer recognizes this correctly, but it does not let me select /dev/sda as boot device. It only offers the NVMe PCIe disk from where I cannot boot. How can I force the installer to select /dev/sda as boot device?

In you setup with nvme, you will need to set boot from nvme.
So grub-install to that and you'll be fine.
If unsure, provide

Code: Select all

sudo parted -l
sudo blkid
cat /etc/fstab

Unfortunately, this did not help because the nvme device is not recognized as boot device in the BIOS. But just by accident I found a solution: After installation of mga6-sta2 on the nvme device and /boot on /dev/sda7 I had to restart the system and to choose "Update system" in the installer. This time I was offered to select the correct boot device (LSI RAID 5/6 SAS 6G). Now everything works as expected.
