• Raid0 (bios option) + UEFI installation


    I have RAID option in bios and I created one with 3 ssd. (RAID0)
    Then I installed ubuntu on it.
    It is a UEFI system and gparted see the /dev/md0 with 3 partition: efi, swap and home.
    Now I wanna install antergos so I thought using the same partition of ubuntu and overwright the home / partition.
    The problem is that the installer doesn’t see those partition. What can I do?

  • Hi,

    Can you please run sudo fdisk -l from your Ubuntu installation? That will show your devices and your partitions.

    Cheers!

  • Here is the fdisk -l

    Ok, I have 3 ssd in raid0 using bios option (drives are sda, sdb, sdc). I created also a little partition with windows (on sdd that is also used as storage).
    If I try to install antergos the installer sees the raid0 with about 330 GB, but where should I install the bootloader? From what I can see from fdisk, I think the bootloader is installed in sda partition (strange). But I tried to select sda from antergos installer and it didn’t boot.
