    Re: Boot failure after GRUB 2.0 installation

    Another option is to try kexec if it comes installed with GParted.
    Something like this:
    Code:
    mount -t ext4 /dev/sda7 /mnt
    kexec -l /mnt/vmlinuz --append=root=/dev/sda7 --initrd=/mnt/initrd.img
    kexec -e

    Code:
    mount /dev/sda7 /mnt
    mount --bind /proc /mnt/proc
    mount --bind /dev /mnt/dev
    mount --bind /sys /mnt/sys
    chroot /mnt
    grub-install /dev/sda
    exit
    umount /mnt/sys
    umount /mnt/dev
    umount /mnt/proc
    umount /mnt
    That is a chroot procedure. Hope fully it will work.

    And get a new usb stick, it least 1GB and make it ubuntu live usb, and keep it.
    When I get to "chroot /mnt" it says
    Code:
    chroot: failed to run command '/bin/bash': Exec command error.

    kexec: command not found.

    Ok just borrowed the neighbors usb (should have thought of that earlier ), installed ubuntu live, then boot-repair and now it's working. Boot-repair summary: http://paste.ubuntu.com/1613807/

    This better teach me a lesson that I should keep an Ubuntu disc with me at all times.

    It looks like you can't do it from Gparted Live, as I assumed. It is not a "full" linux distro.

    I can't understand what is the problem using the same stick for Damn Small Linux or Puppy Linux. You said it would overwrite Gparted Live. So what, it's not even a full distro, as you can see yourself. It serves only for partitioning, and you have partitioning tools in one form or another (GUI or command line) in the mentioned distros too.

    So, you don't lose anything by overwriting Gparted Live, but you can gain much. It's up to you.

    Investigate first and confirm that the distro you want to use can fit on the stick.

    Then that would be #1 on my to-do-list, while my computer's now working. Thanks a lot!
