    mkusb consists of bash shellscripts, that call standard tools, most of them already bundled with Ubuntu and Debian, the rest of them readily available from the standard repositories.

    So there is no compiling. Please tell me which files you would like to see (debian files, that configure the packaging), and I can send them to you so that you can check the dependencies.

    The help package usb-pack-efi might upset the debian gurus, but mkusb works without it for cloning, and when making persistent live drives for Ubuntu (but not Debian). If necessary, I can make it work for Debian too, or simply remove that feature and rely on mkusb-minp for Debian persistent live drives.

    Hi,

    just to avoid the impression that i bailed out of this thread:
    sudodus and i are discussing the mkusb/Debian issue in private mails now.

    Have a nice day

    I'm not sure if I understand this part. The computer I'm on uses BIOS as its firmware, but uses GRUB as its bootloader. At least, I think it uses GRUB as its bootloader. Here's what my bootloader looks like -- not from my computer:



    Also, both the Master Boot Record (MBR) and the EFI System Partition for EFI systems are located on the HDD/SSD or, in this case, USB stick, correct? I just want to make sure I understand how firmware is able to boot a Linux distribution.

    Since, I'm more used to creating live DVDs, I didn't use a utility like mkusb to create the bootable USB, I just used Startup Disk Creator. And, I know I was successful in my endeavor, because I ended up testing it on my home computer, first, to see if it would boot. So, I was successful in creating a bootable USB stick, it just wouldn't boot on my friend's front-facing USB port; I haven't tried the back ones, though. That's why I need a functional DVD drive as backup, in case the USB stick fails to boot in the back. As for the DVD burner itself, it should arrive on Thursday. So, be ready to check back then.

    Also, I tried popping in two DVDs into my CD/DVD drive, and it's weird, one of the DVDs worked, but the drive failed to even respond to the other DVD. Is this another sign of a failing CD/DVD drive, when one DVD works, but the other doesn't? It's weird, though, because the same DVD that my drive wouldn't recognize on Ubuntu, worked just fine on my Windows 7 partition (I dual-boot).

    Re: Can't Create Bootable DVD Of Ubuntu 18.04

    Hi,

    about Ubuntu ISOs and its bootloaders.

    It is of course possible and usual to install GRUB on your hard disk as
    boot loader for being started by PC-BIOS firmware. It is also possible to
    use GRUB as bootloader of an ISO image for being started by PC-BIOS.
    This can be seen with the ISOs from program grub-mkrescue or of the Guix
    project.

    Nevertheless it is a long standing tradition to boot ISOs via PC-BIOS by
    the bootloader ISOLINUX from the SYSLINUX project. When Matthew Garrett
    added EFI booting to the Fedora ISOs, he decided for hard technical reasons
    not to use SYSLINUX for that task. Its EFI code simply fails with CD-ROM.
    See http://mjg59.dreamwidth.org/11285.html for Matthew's success report.
    So GRUB got into Fedora ISOs. Debian and Ubuntu followed a while later,
    using the same combination of boot loaders.

    The typical "mjg" ISO has two El Torito boot images. Inspection by xorriso
    yields:
    Code:
    $ xorriso -indev ubuntu-18.04.3-desktop-amd64.iso -report_system_area plain -report_el_torito plain
    ...
    El Torito images   :   N  Pltf  B   Emul  Ld_seg  Hdpt  Ldsiz         LBA
    El Torito boot img :   1  BIOS  y   none  0x0000  0x00      4      995658
    El Torito boot img :   2  UEFI  y   none  0x0000  0x00   4928      997283
    These images are also exposed by the ISO as data files
    Code:
    El Torito img path :   1  /isolinux/isolinux.bin
    El Torito img path :   2  /boot/grub/efi.img
    The one is a 16-bit x86 program and the other is a FAT filesystem image,
    as specified in UEFI. As the names already suggest, they stem from ISOLINUX
    and GRUB, respectively.

    So far for booting from CD/DVD/BD media. For booting from USB stick, there
    is ISOLINUX x86 code in the MBR of the ISO image. If started by PC-BIOS it
    immediately executes the El Torito boot program isolinux.bin.
    This is indicated in the xorriso report by the word "isohybrid" in
    Code:
    System area summary: MBR isohybrid cyl-align-on GPT APM
    For booting from USB stick via EFI, there is an MBR partition of type EF.
    Code:
    MBR partition table:   N Status  Type        Start       Blocks
    MBR partition      :   1   0x80  0x00            0      4068000
    MBR partition      :   2   0x00  0xef      3989132         4928
    MBR partition path :   2  /boot/grub/efi.img
    UEFI specifies that the firmware shall look into the FAT filesystem of this
    partition for the EFI start program. That's \EFI\BOOT\BOOTX64.EFI for
    64 bit x86 processors. The partition start block 3989132 in 512-byte units
    matches the start block of the EFI El Torito image 997283 in 2048-byte
    units. So both are the same byte range. (El Torito addresses in 2048 but
    counts size in 512. Shrug.)

    ISOs can have an MBR and partition tables, because the ISO 9660 specs
    reserve the first 32 KB of the filesystem range for arbitrary "System Use".

    -------------------------------------------------------------------------

    It is indeed a bad sign if the drive sometimes recognizes a particular
    medium and sometimes does not. It is not plausible that it would work
    reproducibly better with MS-Windows than with GNU/Linux. The recognition
    happens in the drive by its own firmware. Operating systems and burn
    programs inquire the recognized status by standardized SCSI commands.
    There is few room for artsy variations with this task.

    But statistics can be a bitch. It might need a lot of tries until you
    get similar success/failure rates in both groups of experiments.

    Have a nice day

    Re: Can't Create Bootable DVD Of Ubuntu 18.04

    Just received the DVD burner, but I'm a bit nervous; when I opened the box from Amazon, and looked at the back of the box from the manufacturer (inside the Amazon box), it only said DVD-RW. That's weird, because on the product page on Amazon, it specifically says, "DVD+/-RW." I'm really worried now that there's a chance the drive may not be compatible with both formats. Now that I think of it, this reminds me of an article I read in Ars Technica, a while back, about how many third-party sellers on Amazon intentionally mislabel their products in order to get more people to buy them. I thought almost all DVD drives sold today were compatible with both formats, so maybe the drive is still compatible with both formats.

    Anyway, I did a

    Code:
    sudo tail -f /var/log/syslog
    to get the device name of the external drive, and repeated the instructions from before using the same xorriso-burned DVD from earlier by typing:

    Code:
    xorriso -outdev /dev/sr1 -toc
    which gave me:

    Code:
    xorriso 1.4.2 : RockRidge filesystem manipulator, libburnia project.
    
    xorriso : NOTE : Disc status unsuitable for writing
    Drive current: -outdev '/dev/sr1'
    Media current: DVD+R
    Media status : is written , is closed
    Drive current: -outdev '/dev/sr1'
    Drive type   : vendor 'HL-DT-ST' product 'DVDRAM GT80N' revision '1.01'
    Drive id     : 'KZ5D9H24934 '
    Media current: DVD+R
    Media product: AML/003/48 , UML
    Media status : is written , is closed
    Media blocks : 0 readable , 0 writable , 0 overall
    TOC layout   : Idx ,  sbsector ,       Size , Volume Id
    xorriso : SORRY : Cannot obtain Table Of Content
    xorriso : NOTE : Tolerated problem event of severity 'SORRY'
    xorriso : NOTE : -return_with SORRY 32 triggered by problem severity SORRY
    and, then, proceeded to type:

    Code:
    xorriso -outdev /dev/sr1 -check_media use=outdev --
    which gave:

    Code:
    xorriso 1.4.2 : RockRidge filesystem manipulator, libburnia project.
    
    xorriso : NOTE : Disc status unsuitable for writing
    Drive current: -outdev '/dev/sr1'
    Media current: DVD+R
    Media status : is written , is closed
    xorriso : FAILURE : No content detected on media
    xorriso : aborting : -abort_on 'FAILURE' encountered 'FAILURE'
    Edit: I just looked up the model and manufacturer with the help of the above information to check if the drive is compatible with both formats. At first, it's not at all obvious what the model and manufacturer of the drive is, but it looks like the drive is compatible with my DVD+Rs. I think Roofull is one of those white-label companies that rebrands drives that are sold to multiple companies.

    Hi,

    > using the same xorriso-burned DVD from earlier
    Code:

    Drive id     : 'KZ5D9H24934 '

    Well, that medium is dead. Closed and 0 bytes.

    > it only said DVD-RW.

    They simply do all DVD types, nowadays.
    You can inquire its list of supported media by:
    Code:
    xorriso -outdev /dev/sr1 -list_profiles
    which with a typical DVD burner should look like:
    Code:
    Profile      : 0x0015 (DVD-R/DL sequential recording)
    Profile      : 0x0016 (DVD-R/DL layer jump recording)
    Profile      : 0x002B (DVD+R/DL)
    Profile      : 0x001B (DVD+R)
    Profile      : 0x001A (DVD+RW)
    Profile      : 0x0014 (DVD-RW sequential recording)
    Profile      : 0x0013 (DVD-RW restricted overwrite)
    Profile      : 0x0012 (DVD-RAM)
    Profile      : 0x0011 (DVD-R sequential recording)
    Profile      : 0x0010 (DVD-ROM)
    Profile      : 0x000A (CD-RW)
    Profile      : 0x0009 (CD-R)
    Profile      : 0x0008 (CD-ROM)
    Profile      : 0x0002 (Removable disk)
    An SCSI profile is a set of SCSI features which bundle sets of SCSI commands
    and parameters. Sometimes one medium type can be burned according to more
    than one profile. (DVD-ROM, CD-ROM, Removable disk are read-only profiles.)
    But roughly you can tell that if it says "DVD+R" then it believes to
    be able to burn DVD+R according to the good habits described in MMC-6.


    > I think Roofull is one of those white-label companies that rebrands
    > drives that are sold to multiple companies

    It is made by LG. "HL-DT-ST" = Hitachi-LG Data Storage.
    https://en.wikipedia.org/wiki/Hitachi-LG_Data_Storage
    https://www.lg.com/us/burners-drives...nal-dvd-writer

    Now try whether it burns a yet unused DVD+R with your favorite burn program.

    Have a nice day

    Re: Can't Create Bootable DVD Of Ubuntu 18.04

    I used K3b to burn and verify the disc, and was able to successfully boot from the resulting burned DVD. So, what do you think the problem was, a malfunctioning CD/DVD drive?

    Also, when you write:

    Quote Originally Posted by scdbackup

    by closed, you mean the xorriso-burned DVD can no longer be written to, correct?

    Lastly, I'm having trouble verifying the md5sums using CatKiller's method with:

    Code:
    md5sum -c /media/mason/"Ubuntu 18.04.3 LTS amd64"/md5sum.txt
    This is what I get if I type the above command:

    Code:
    md5sum -c /media/mason/"Ubuntu 18.04.3 LTS amd64"/md5sum.txt
    With that command you're checking the md5 hashes listed in the text file against the files that are in whichever directory you're in (likely ~/).

    Something like
    Code:
    cd /media/mason/"Ubuntu 18.04.3 LTS amd64"/
    md5sum -c md5sum.txt
    is what you're after.

    If you're able to boot from it, there's a "check for errors" option that does the same thing.

    @CatKiller
    That makes much more sense.

    I think I will do this from now on, instead of using K3b to verify the disc for me. Is md5sum capable of highlighting files whose md5sums don't match, or do I have to use a utility such as grep to find any files that haven't been burned properly? If so, it would help if I knew what I was looking for, i.e. something like:

    Code:
    md5sum -c md5sum.txt | grep 'NOT OKAY'
    That's just an example, of course. I don't know what a non-matching md5sum looks like.

    Actually, nor do I. I think that if any individual line has a problem that is also listed at the end of the output, though.

    Having the list of MD5 sums is something that the distros do specifically so that they can embed a utility to check the disc for errors as part of the installation process. It wouldn't be there on an arbitrary burned disc.
