I think I killed my bootloader - How installing again ?

  • OMV 1.20


    I think I'm unfortunately killed my bootloader on my N40-L system disk while experementing
    with a test version of https://www.terabyteunlimited.com/bootit-bare-metal.htm


    I thought this could be a good alternative for me as a linux noob to save my systemdisk and have
    the programm for permanent use on the systemdrive in an extra partition. Seems to look to good
    to be true ? But if you read the specs on their website it should be possible.



    I receive the massage : missing operting system


    Is it the Linux or Swap partition where the system starts from ? Both partitions are still on the disk.


    Is there any possibilty to install the Debian / OMV bootloader again on the system disk or must I do a fresh istall ?


    How can I save all my data on the data drives ?

    Boot the Debian Wheezy netinst image and pick repair from the options. You can fix your bootloader that way. No matter what, you won't lose your data. If you had to reinstall, you would disconnect your data drives and reconnect after installation.

  • There are a couple tools I use that might help:


    Super Grub2 - I have a couple extra partitions on my OMV NAS and one has mint installed. For the life of me I cant get grub config to see it. So I just boot super grub and search for the drives and it pops up the other system and I can boot it. I should try boot repair on it eh?!!

    Boot Repair Disk - I used this just yesterday when I used clonezilla to restore a partition to a drive. Since I didnt restore the mbr like your problem it just said missing os. BRD found and rebuilt the mbr/grub and I was able to boot the partition I had just restored. Plus its GUI based so extremely easy to use.

    You can write the image to a usb stick. The boot-repair-cd might be even easier.

  • I installed the netinst on the usb stick, but can't find a "repair" fuction.


    netinst wanted to install a complete Debian and will partition my disk ? ?
    Couldn't find the repair function ? ?


    So I tried the boot-repair-disk - works perfect for me ! I'm on the air again.
    THX ryeoaaron and earbiter !


    Nevertheless I'll play around again a bit with Bootit Baremetall. Now I know to fix.

  • Willri, glad to hear the boot repair worked for you! I tried it on my OMV and it showed both bootable raids (MD3=OMV and MD4=MINT) so I THOUGHT it was working. It completed the repair process and I STILL only see the option to boot OMV. I will keep messing with it..
