    trying to get rid of sda

    ok

    i have samsung m3 usb 3.0 external connected to my laptop it mark as sdb2 and i want it as only as sdb visible
    how do i do it?
    im trying get rid off sda on external harddisk with sdb

    ive tried with
    sudo mount /dev/sdb2 /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
    grub-install --recheck (no errors)
    update-grub
    exit &&
    sudo umount /mnt/sys &&
    sudo umount /mnt/proc &&
    sudo umount /mnt/dev/pts &&
    sudo umount /mnt/dev &&
    sudo umount /mnt

    originally it was with sdc, sda, sdb and all internal harddisk os' and another external harddisk connected to my latop

    sdb2 has Kali GNU/linux in it

    just wanna get rid off sda

    should there be any logs about it?

    Re: trying to get rid of sda

    In linux /dev/sda means a Hard drive or SSD or USB-external. /dev/sda1, /dev/sda2 and so on, means partitions on /dev/sda.
    /dev/sdb means a second HDD, and the partition on /dev/sdb will be represented as /dev/sdb1, /dev/sdb2 and so on.

    I think you are confusing /dev/sdb1 with /dev/sda (/dev/sdb1 is a first partition on /dev/sdb while /dev/sda is another HDD altogether).

    Post the output of:
    Code:
    sudo parted -l
    sudo fdisk -l

    actually should have more specific

    i choose boot with F9 which from external hardisk instead of internal, so sdb is there and there is sdas

    Post the output of the commands I requested and tell us what exactly you want to get rid of after looking at the output.

    Boot into Ubuntu, open Terminal [ctrl+alt+T], run the commands one after another, copy and paste the output each command gives here.

    Like this:

    Code:
    $ sudo parted -l
    Model: ATA Hitachi HDS72101 (scsi)
    Disk /dev/sdb: 1000GB
    Sector size (logical/physical): 512B/512B
    Partition Table: msdos
    Disk Flags: 
    
    Number  Start   End     Size    Type      File system     Flags
     1      1049kB  21.5GB  21.5GB  primary   ext4            boot
     2      21.5GB  43.0GB  21.5GB  primary   ext4
     3      43.0GB  64.4GB  21.5GB  primary   ext4
     4      64.4GB  1000GB  936GB   extended
     5      64.4GB  996GB   931GB   logical   ext4
     6      996GB   1000GB  4298MB  logical   linux-swap(v1)

    Re: trying to get rid of sda

    From reading through your posts several times, I'm not sure exactly what you are trying to accomplish. If you want to boot an operating system on the sdb drive (the 1TB) drive, then disconnect sda, the 500GB drive. Otherwise it will show.
