    Cannot boot ubuntu after remove a failing disk

    Our ubuntu server has four hard disks, but we didn't make them a RAID. Yesterday, one of the disk was reported to be failing, and this disk was /dev/sdb and was mounted as /data (was used to store data), but the server cannot boot up after we remove this disk. We tried umount it or deleted it in the 'Disk ultility', but didn't work. Is there any way to just remove this disk and avoid reinstall the ubuntu. Thank you very much!

    This happened with the damaged disc that changed, I changed the GRUB, I think. just regenerate it using a Ubuntu LiveCD. you enter the option: Try Ubuntu and run:

    Code:
    sudo mount /dev/sda1 /mnt
    sudo mount --bind /dev /mnt/dev
    sudo mount --bind /dev/pts  /mnt/dev/pts
    sudo mount --bind /proc /mnt/proc
    sudo mount --bind /sys  /mnt/sys
    sudo chroot /mnt
    grub-install --recheck /dev/sda
    then from the new grub choose the option reconfigure grub or boot file.

    Do you have a liveCD or USB of the same version of Ubuntu as your server install. If so run this from that liveCD or download the full repairCD. Then post link to BootInfo report.

    Were you booting from BIOS the sdb drive? Then grub maybe was installed to wrong drive? BootInfo report will give us those type of details.
