    I do not know LVM, but with a separate /boot partition the grub in the MBR should be looking at the boot partition to boot not the root partition inside the LVM. Years ago grub would not directly boot into LVM partition, but know had drivers to do that. But most installs still configure a separate /boot with grub & kernels outside the LVM.

    I do not know if Boot-Repair issue, grub issue or LVM issue. You can try manually installing grub to MBR from live installer. This is if live installer is sda, and drive is sdb, if next time you boot it reverses change drive in example below to sda.

    Combining /boot instructions with LVM may be this?
    Not sure if Live installer now includes the LVM driver or not
    sudo apt-get install lvm2
    Mount LVM
    sudo vgchange -ay


    sudo mount /dev/mapper/lm13-root /mnt

    sudo mount /dev/sdb1 /mnt/boot
    sudo grub-install --boot-directory=/mnt/boot /dev/sdb

    Is there some reason for LVM? You only have / & swap. With new drives I now prefer gpt partitioning. One of the old advantages of LVM was a work around to the 4 primary partition limit with MBR(msdos).

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

    This tool worked fine to repair Grub so I could boot up again after
    restoring a hard disk image using Paragon Backup & Restore 2014
    Free. However, it didn't work to change my default OS to Windows 7. I
    tried twice and it still timed out and booted into Ubuntu by default. I
    have since found out how to do this manually.

    @dec!"
    Is your install in sda1? I do not know about ReiserFS and how to fix it. The standard tools are for ext family of partition formats and most just use ext4. You may even need to add extra drivers to Boot-Repair to get it to mount partition correctly.

    Linux does not use boot flag. Best to move boot flag to sda3 as that is your Windows install. Then the syslinux boot load will boot Windows if it has no other issues.

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

    Hello everyone

    I'm trying to be new user of Ubuntu family systems from a long time.
    I have problem with instalation of Xubuntu on the same drive, next to existing Windows XP.
    I have a Windows XP on my sda1 (NTFS) partition, and trying to install Xubuntu on my sda5 (ext4).
    During instalation I am choosing sda for boot menu (mayby it's wrong choise).
    After instalation there is always problem with grub (no such partition). Then I am restoring MBR (from rescue CD or boot-repair-disk) and use only Windows till I will try next instalation.
    Magic one-button on Boot Repair doesn't work (still grub error: no such partition).

    What can I do with it. I want to use Xubuntu or Windows whenever I want (choosing system from boot menu).
    If there is a chance to fix it easily please let me now.

    What mode in BIOS is hard drive. Preferred setting is AHCI if available or large or LBA. But not RAID nor IDE.

    Some older BIOS do not boot from any partition that is beyond 137GB on drive. Is this drive a newer drive on an older system?
    You have used all 4 primary partitions, so a bit of work to rearrange, but you would need a /boot or a smaller / (root) partition fully with in the first 137GB of the drive. All your boot files are over 200GB on drive.

    Your sda3 does not look like it has much data, so you may be able to back that data up and delete it. Then shrink sda1 by 300MB and create a new sda3 after sda1 as /boot. You can use gparted from your live installer.

    Probably easier to re-install but you can move all boot files from the /boot folder to the new boot partition, add an entry to fstab and reinstall grub with Boot-Repair. If that seems like too much then the reinstall will be easier. You do have to use Something Else. You can choose the same / & /home, it will find swap automatically and you have to also then mount the new partition as /boot. Plus anytime you have to update grub remember to also include that.

    Ok. Now everything is working perfect.
    Probably the key was to have /boot in first 137GB. I have a HP nx6310 notebook (originaly it was with 80GB HDD).
    Now I can use both systems.
    Thank you for your advice.
