    Did you check off that you have the separate /boot. But it does not look like grub2 is installed at all, so just an update of grub to the MBR is not working.

    Boot-Repair can help you chroot into your install and reinstall grub2 from command line.

    Once chrooted, sudo not required:
    apt-get update #resync package index
    apt-get upgrade #newest versions of all packages, update must be run first

    apt-get install grub-pc grub-common
    or
    apt-get install --reinstall grub-pc grub-common

    Re: [Boot-Repair] Graphical tool to repair the PC boot in 1 click!

    Hello all,

    I have setup a new dynamic partition in windows and afterwards the grub doesn't start at all. The PC restarts again and again.

    I have run boot-repair, unfortunately it didn't work:
    1st attempt - grub install failed both on sda1 and sda2
    2nd attempt I didn't come to grub install.

    the url is
    paste.ubuntu.com/1670859/

    my release is 10.04 LTS

    Thanks
    Rudi

    Dynamic partitions do not work with LInux. And per Microsoft it is a one way conversion. You have to back up everything. Delete all partitions, create new basic partitions, reinstall and restore your data.

    Microsofts offical policy is a full backup, erase dynamic partitions and create new basic partitions. There is no undo.
    Dynamic volume is a Microsoft proprietary format developed together with Veritas (now acquired by Symantec) for logical volumes.
    You may be use a third-party tool, such as Partition Wizard MiniTool or EASEUS to convert a convert a dynamic disk to a basic disk without having to delete or format them.
    I've never used any of these and so I can't be sure they will work.Be sure to have good backups as any major partition change has risks.

    It seems most of the Windows conversion tools are changing that only the paid version supports the dynamic partition change. You may want to search download sites for older version.

    Used EASEUS Partition Master - free version used to include conversion

    Several users have used this, it has a liveCD download to use but you have to use the non-free version:
    MiniTool Partition Wizard Professional Edition 5.2 to convert without loss of data the disk from dynamic disk to a basic disk.
    also used Partition Wizard to set an existing partition logical instead of primary

    Re: [Boot-Repair] Graphical tool to repair the PC boot in 1 click!

    Just wanted to update this thread on my issue in case it can help someone else.

    To review, I installed kubuntu 12.10 to my hard drive, but the drive would not boot. Boot Info Script kept reporting "No boot loader is installed in the MBR of /dev/sda" even after I tried to redo grub, run Boot-Repair, etc.

    I ended up fooling around with the bios settings, reinstalling ubuntu (this time it was xubuntu 12.10)...this time it worked.

    Not 100% sure why it worked the second time and not the first, but I suspect it might have been the bios settings. On the first install I had

    Boot Mode Selection : UEFI and Legacy

    ...which I changed to

    Boot Mode Selection : Legacy only

    (For the record my motherboard is a Gigabyte 970A-D3 , Rev. 3.0)

    I don't fully understand UEFI and how it works. There is some info on it here, but this seems to deal more with dual boot windows/ubuntu situations, not exactly what I was dealing with...and some of the stuff it talks about, like "Secure Boot", are not it my bios...so I'm not completely clear on if that's just a different name for UEFI or not.

    Does UEFI prevent you from changing the MBR somehow?

    So in any event, now I have "Legacy only" boot in the bios, and ubuntu does boot correctly.

    What I still wonder is -- will I have problems in the future not having UEFI boot? Will it be a problem, for instance, if I wanted to install windows to dual boot on this machine? What about windows in virtualbox or something like that?

    If UEFI was the problem originally (again, I can't say for sure it's the case since I haven't tried to reinstall again- having already spent many hours on this I don't really have the time to do too many more time-consuming experiments), should not the ubuntu installer have detected this an either set it up correctly or warned me?

    Anyhow, it is at least working now. Like I said I'm mostly posting this just in case it might help someone else. However, if anyone has knowledge of UEFI and can provide further insights they would certainly be most welcome to do so!

    UEFI is a totally differnt way to boot. It does not use MBR, but has an efi partition that serves the same purpose as the MBR, but in effect is like having many MBRs as every system can have its boot loader in the efi partition.

    Part of the issue with UEFI is that it needs gpt partitioning. Windows will only boot from UEFI with gpt partitioning and with gpt partitioning will only boot with UEFI.
    Ubuntu will boot in either BIOS or UEFI from gpt partitions.

    If you have installed in BIOS mode and want Windows in the future you should have drive with MBR(msdos) partitioning.
    If installing with gpt partitioning you may want efi partition at start of drive even if in BIOS mode now. It is not large and give flexibility to change to UEFI in future.

    Re: [Boot-Repair] Graphical tool to repair the PC boot in 1 click!

    Hi oldfred, please let me know if this thread is not the appropriate place for this discussion. But since it seems UEFI is growing in prevelance, it might be useful for many people, as well as myself, to clarify some of these points.

    First, do you know if the ubuntu installer understands and recognizes UEFI and gpt partitions? I don't think it offered me those options when I did the install. It would seem that this would be the correct place to handle those issues.

    Second, I did google gpt partitions and tried to learn about them. It isn't clear to me, are gpt and mbr mutually exclusive schemes? If I have an mbr partitioned disk, must I nuke it and reinstall everything if I want it to have gpt partitions? Or can I set up gpt on some partions and keep mbr on others? Or, if I can only have one, can one convert one schem to the other or do you need to start from scratch?

    Third, and sorry for my ignorance, but if I can boot ubuntu and windows from "Legacy" mode, why would I want UEFI?

    Re: [Boot-Repair] Graphical tool to repair the PC boot in 1 click!

    hello,
    i wanted to install linux and win7 on my system.
    but after installation of linux, grub2 didnt show win7. now i tried the boot-repair, but still no change to the grub2-list at start.

    @Bartle
    I would install a Windows boot loader to sda only and see if Windows boots directly. Script shows partition and files are there. Perhaps the FIBMAP: error is preventing the os-prober from finding Windows? You can manually add a Windows boot stanza to 40_custom.

    gksudo gedit /etc/grub.d/40_custom
    #update grub menu
    sudo update-grub

    I changed UUID to yours from Boot scrip.
    Code:
    menuentry "Windows 7 (loader) (on /dev/sda1)" {
        insmod ntfs
        set root=(hd0,1)
        search --no-floppy --fs-uuid --set 64E8BAF3E8BAC31A
        chainloader +1
    }

    If you have a new UEFI/BIOS system, you can get two boot options on Ubuntu (and Windows) installers. One will be UEFI and the other BIOS/legacy/CSM or whatever. How you boot from UEFI menu is how it installs.

    MBR and gpt are totally different ways to partition a drive. Entire drive must be one or the other, but I have several drives, some gpt and some MBR.

    Converting to or from GPT
    http://www.rodsbooks.com/gdisk/mbr2gpt.html
    You then need to use gdisk to convert from gpt to MBR

    If legacy works, then you do not have to have UEFI.

    UEFI and gpt are the new ways, BIOS and MBR are now very old, but well understood. But gpt is recommended for SSD and required for drives over 2TiB. Windows only boots from gpt drives with UEFI. I now use gpt on all my new drives, but still have BIOS. And newest drive I left an efi partition as I may move drive to a new system this year & it will be UEFI.
