    Re: busybox with raid 0

    Are you using the standard desktop cd or the alternate install cd?

    Re: busybox with raid 0

    I forgot to ask the first time sorry, is this bios raid (fakeraid) or software raid?

    Softraid doesn't work in raid0 unless you have separate /boot partition outside the array. Even with fakeraid I think this can be the issue. In raid0 files are split on the disks and I'm not sure the boot files like that.

    Regardless whether you use fakeraid or softraid, try this:
    Use the alternate cd to install, it has raid support.
    Create 200MB raid1 device for /boot.
    Create the rest as raid0 device for root.

    Towards the end of the install watch out whether the bootloader (grub2) gets installed successfully. I think the problem is that the bootloader isn't installed OK.

    If you don't wanna try another setup, we can check of grub2 is installed but I would try the setup with raid1 for /boot first.

    Re: busybox with raid 0

    No, software raid is referred to a raid configured with the ubuntu OS.
    The bios raid is fakeraid because in a way it is software raid and not dedicated hardware raid. But to make the distinction, it's not the same as softraid with the linux OS.

    When asked where you want to install the bootloader, did you select the /dev/mapper device and not a particular disk (sda, sdb)? You need to install it on the raid device.

    I would still try the suggestion from my previous post about the /boot device.

    Sure. Just open terminal, issue the command and post the ouput. It's best to include the result in code tags, or select the text and hit the # button in the toolbar above when writing the post.
