ISO from DVD to local file

    Make ISO from DVD

    In this case I had an OS install disk which was required to be on a virtual node with no optical drive, so I needed to transfer an image to the server to create a VM

    Find out which device the DVD is:

    lsblk
    

    Output:

    NAME            MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
    sda               8:0    0 465.8G  0 disk 
    ├─sda1            8:1    0     1G  0 part /boot
    └─sda2            8:2    0 464.8G  0 part 
      ├─centos-root 253:0    0    50G  0 lvm  /
      ├─centos-swap 253:1    0  11.8G  0 lvm  [SWAP]
      └─centos-home 253:2    0   403G  0 lvm  /home
    sdb               8:16   1  14.5G  0 disk /mnt
    sr0              11:0    1   4.1G  0 rom  /run/media/rick/CCSA_X64FRE_EN-US_DV5
    

    Therefore /dev/sr0 is the location , or disk to be made into an ISO

    I prefer simplicity, and sometimes deal with the fallout after the fact, however Ive repeated this countless times with success.

    dd if=/dev/sr0 of=win10.iso
    

    Where if=Input file and of=output file

    I chill out and do something else while the image is being copied/created, and the final output:

    8555456+0 records in
    8555456+0 records out
    4380393472 bytes (4.4 GB) copied, 331.937 s, 13.2 MB/s
    

    Fin!
