    If me. I would boot any live cd in my rack. Probably Pmagic or Puppy or AntiX.

    Run as root in terminal

    Code:
    blkid
    write down what it spits out on a notepad. Compare it to your uploaded screeny.

    Howdy and Welcome.

    If the blkid output does not show the uuid in the error message, check the /boot/grub/grub.cfg and /etc/fstab files to see if it there and what it was and change it to the new one.

    thx guys for the suggestions. I am not so familiar with this command, but as i understand i need to:
    1. Download some live CD, boot from it
    2. Run the command blkid from it ?
    3. Have to check /boot/grub/grub.cfg and /etc/fstab but for what ?

    BR

    What you need to look for is the UUID number that is on your piece of paper and compare it to what it says in /boot/grub/grub.cfg and also UUID in /etc/fstab.

    If the numbers don't match. Which is probably why

    bricked to the boot screen.
    Your UUID on your screenshot says /dev/disk/by UUID does not exist. Which means wrong number.

    Hope that helps.

    From any Linux Live CD, run the blkid command and note the output. Particularly, look to see if the uuid listed in the error message you posted above shows, the number/letter combination after: /dev/disk/by-uuid

    Mount the Debian partition which contains your boot files and look in the /boot/grub/grub.cfg file to see what uuids are listed in any of the menuentries, compare to the one in the error message. Same thing in the /etc/fstab file. See if the / or swap partition has the uuid from the error message. Not sure this will be the problem but could eliminate a possibility. I don't use Debian myself but recall installing it and it changed by swap uuid and prevented booting another OS. What you look for in the grub.cfg file would be lines like the two below to compare the error uuid with the ones in the menuentry(s).

    search --no-floppy --fs-uuid --set=root 47891df9-aa27-4df9-99ac-aa96276780ac
    linux /boot/vmlinuz-3.2.0-44-generic root=UUID=47891df9-aa27-4df9-99ac-aa96276780ac

    Hi guys,

    So booted with AntiX, and blkid returned me this:
    UUID is defintely different.

    /dev/loop0: TYPE="squashfs"
    /dev/sda1: UUID="f39c6a63-be4f-a645-a999-e440c4dcff89" UUID_SUB="09e8fa44-c252-dc51-f432-1b1c85ffc33f" LABEL="netshop:2" TYPE="linux_raid_member"
    /dev/sda2: UUID="56d35784-44f8-27a4-eb07-047f38523f13" UUID_SUB="a8207850-1438-7615-c668-99b1f2fff6c3" LABEL="netshop:1" TYPE="linux_raid_member"
    /dev/sdb1: UUID="f39c6a63-be4f-a645-a999-e440c4dcff89" UUID_SUB="b694b12d-9398-c9bb-d935-32e6eaef0caa" LABEL="netshop:2" TYPE="linux_raid_member"
    /dev/sdb2: UUID="56d35784-44f8-27a4-eb07-047f38523f13" UUID_SUB="f0e795d7-56c3-e192-f551-16ca4c5cf6ad" LABEL="netshop:1" TYPE="linux_raid_member"
    /dev/sr0: LABEL="antiXlive" TYPE="iso9660"

    tryin to mount sda1 return me:
    demo@antiX1:~
    $ sudo mount /dev/sda1 /media/netshop
    [sudo] password for demo:
    mount: unknown filesystem type 'linux_raid_member'
    demo@antiX1:~

    Maybe i need to assemble first with mdadm the raid ?

    Did you find the old uuid in either grub.cfg or fstab? You haven't posted that info so?? I don't use RAID so can't offer any other suggestions.

    Same here. You are halfway there though. I usually use the root terminal myself in AntiX or use sux in regular roxterm instead of sudo.
    Sudo was enabled in AntiX only recently in 13.2 so I am not used to using it being a long time user.

    So, tried again pmagic livecd, huge improvement, now successfully mounted MD2 and the result from blkid is also different:

    root@PartedMagic:~# blkid
    /dev/sda1: UUID="f39c6a63-be4f-a645-a999-e440c4dcff89" UUID_SUB="09e8fa44-c252-dc51-f432-1b1c85ffc33f" LABEL="netshop:2" TYPE="linux_raid_member"
    /dev/sda2: UUID="56d35784-44f8-27a4-eb07-047f38523f13" UUID_SUB="a8207850-1438-7615-c668-99b1f2fff6c3" LABEL="netshop:1" TYPE="linux_raid_member"
    /dev/sdb1: UUID="f39c6a63-be4f-a645-a999-e440c4dcff89" UUID_SUB="b694b12d-9398-c9bb-d935-32e6eaef0caa" LABEL="netshop:2" TYPE="linux_raid_member"
    /dev/sdb2: UUID="56d35784-44f8-27a4-eb07-047f38523f13" UUID_SUB="f0e795d7-56c3-e192-f551-16ca4c5cf6ad" LABEL="netshop:1" TYPE="linux_raid_member"
    /dev/md2: LABEL="System" UUID="69529156-707c-497f-bb71-cf75069e53dc" SEC_TYPE="ext2" TYPE="ext3"
    /dev/md1: UUID="1793e7e7-d17f-4998-96d5-80e8c842bc20" TYPE="swap"
    /dev/sr0: UUID="2014-02-26-10-56-56-00" LABEL="Parted Magic 2014_02_26" TYPE="udf" PTTYPE="dos"
    root@PartedMagic:~#

    Also - "mount /dev/disk/by-uuid/69529156-707c-497f-bb71-cf75069e53dc /media/md2" working without problem

    attached the content of grub.cfg and fstab.
