    Question Boot-repair error

    When I attempt to run boot-repair, I get the following:



    Everything else seems fine. (I run boot-repair sometimes after installing an additional OS to set my default OS).

    gdisk reveals:


    [~] $ sudo gdisk /dev/sda
    [sudo] password for zzz:
    GPT fdisk (gdisk) version 0.8.7

    Partition table scan:
    MBR: protective
    BSD: not present
    APM: not present
    GPT: present

    Found valid GPT with protective MBR; using GPT.

    Command (? for help): p
    Disk /dev/sda: 488397168 sectors, 232.9 GiB
    Logical sector size: 512 bytes
    Disk identifier (GUID): xxxyyyzzz
    Partition table holds up to 128 entries
    First usable sector is 34, last usable sector is 488397134
    Partitions will be aligned on 2048-sector boundaries
    Total free space is 4225 sectors (2.1 MiB)

    Thoughts?

    Re: Boot-repair error

    You are showing an efi partition which is for UEFI boot.

    But you must be trying to convert or Boot into BIOS boot mode as that requires a bios_grub partition for grub to install correctly for BIOS boot. Boot-Repair cannot create that partition, you must have it first. But you should not need it.

    But if system is UEFI, you should not be booting in BIOS mode.

    Post the link to the Create BootInfo report. Is part of Boot-Repair:

    Re: Boot-repair error

    I'm not intentionally trying to boot into BIOS or convert to BIOS. Does boot-repair not work with UEFI boot? Documentation states that it does. All I'm trying to do is use boot-repair to reinstall GRUB (and point to a different OS as default boot).

    Re: Boot-repair error

    In UEFI menu you will get two options to boot Ubuntu flash drive. One should say UEFI and the other not UEFI, but may not be clear that it is BIOS/Legacy/CSM type boot.

    Shows install with screen shots for both BIOS & UEFI, so you know which you are using.
    https://help.ubuntu.com/community/UEFI

    Another user with a Verbatim flash drive said he had these choices.
    1. UEFI: VerbatimStoreNGo
    2. VerbatimStoreNGo

    Re: Boot-repair error

    Maybe my first and second posts are confusing. I'm not having a problem installing an OS (I'm not even trying to install an OS). I'm currently successfully booting ubuntu 13.10 using UEFI. The description of my problem is simple; when I run boot-repair from Ubuntu 13.10 installed on my SSD, I get the error message that I posted in my first post. My SSD is configured as I posted running "gdisk", which shows no issues. I have no other known problems.

    It appears boot-repair is expecting something configured in a way that nothing else expects.

    Re: Boot-repair error

    That can only occur if you boot Boot-Repair in BIOS mode as to correctly install grub-pc(BIOS) you have to have the bios_grub partition.
    You should not get that info message if booted in UEFI and are not trying to convert to BIOS mode.

    Re: Boot-repair error

    First, thanks for your help! I must be doing something simple wrong. Here are my boot settings. I read this as I'm booting in UEFI secure mode:




    And here are the boot-repair options that I'm using (I don't change anything here other than unselecting everything under 'other')

    Re: Boot-repair error

    Please attached screen shots, not post in line. You can easily attach with paper clip icon in Advanced Editor.
    Not all users have high speed Internet and screen shots inline slow download a lot.

    Your UEFI settings look correct, If you want secure boot.
    You may need to check efi or the efi partition option as it looks like you only have BIOS type entries.
    Boot-Repair will convert a UEFI boot to BIOS and vice versa. But it totally un-installs grub & re-installs correct version.
    grub-pc for BIOS boot, but a bios_grub partition must exists
    grub-efi for UEFI boot, but an efi partition must exist
    And with secure boot in it includes the addition of signed version of grub & kernels.
    Boot-Repair is really just running chroots & grub install commands, it cannot create partitions, so will complain if a required partition is missing for grub reinstall. If you just reinstall grub yourself, it tries and fails if correct partitions do not exist as it assumes you know you need that partition.

    Post link to BootInfo report.

    Re: Boot-repair error

    Reviving this thread...I need to do a clean install of 14.04, and would really like to get this issue figured out/fixed before I do that install. Any one have ideas/thoughts?

    Re: Boot-repair error

    First step is how you boot install flash drive.
    If you boot it in UEFI mode it will install in UEFI mode.
    If you boot it in BIOS mode it will install in BIOS mode.

    Review these again:
    Shows install with screen shots for both BIOS(purple) & UEFI(grub menu), so you know which you are using.
