    Re: Howto make USB boot drives

    Hi linmanfu alias Matthew,

    I'm glad that you want to edit the mkusb quick start manual

    I'm uploading it at

    phillw.net/isos/linux-tools/mkusb/mkUSB-quick-start-manual-12.odp

    We can decide to use some other location in the future, for example at the locations you suggested or google drive, where both of us can access the same document.

    Re: Howto make USB boot drives

    mkusb version 12.3.7, 12.3.8

    mkusb 12.3.7
    - dus-persistent: menu_entry_1: new menuentry with toram nopersistent
    - grub.cfg: new menuentry with toram nopersistent
    mkusb 12.3.8
    - modifications for nvme drives (alongside mmcblk) in dus, dus-live, dus-persistent, dus-restore

    A new feature in Ubuntu 19.10 causes the creation of a partition with the label 'casper-rw' if there is unallocated drive space available. This happens not only with the boot option 'persistent' but it is the default (without any particular 'casper' boot option). A live drive will mount the 'casper-rw' parition to /var/crash which can be unmounted and /var/log which will be busy, so that it cannot be unmounted.

    But there is a boot option to make the live drive truly live-only: nopersistent, and I have added a menuentry for mkusb to make it easy for you in order to

    - backup, restore or repair the partition for persistence
    - unmount all partitions on the boot drive so that it can be unplugged or used as a target for a new installation.

    nvme drives are getting more popular, and it is time for mkusb to manage such drives. It will still be very uncommon with persistent live system in nvme drives, but it will probably be more common to wipe such a drive using mkusb.



    Unstable 1: You get/update this new version of mkusb from the unstable PPA via the following commands

    Code:
    sudo add-apt-repository universe     # this line only for standard Ubuntu
    
    sudo add-apt-repository ppa:mkusb/unstable
    sudo apt-get update
    sudo apt-get install mkusb           # to install
    # sudo apt-get dist-upgrade          # upgrade to current version (with all other upgrades), only for installed systems
    
    sudo apt-get install mkusb guidus dus mkusb-common  # to upgrade all mkusb basic components including dus
    
    sudo apt-get install usb-pack-efi    # for persistent live drives that work in UEFI and BIOS mode with 32-bit iso files
    and you get only the version dus (alone or with guidus) via one of the following commands (if you don't care about mkusb-11, mkusb-nox, mkusb-bas)

    Code:
    sudo apt-get install dus
    sudo apt-get install guidus
    Unstable 2: This new version of mkusb might also be available via this link: mkusb/gui#from_phillw.net.
    Unstable 3: There are tarballs with only dus and guidus (mkusb version 12) as a last alternative.



    Stable: mkusb version 12.3.8 is in the stable PPA. The policy is to test mkusb for a long time and in several environments before it is uploaded to the stable PPA (unless there are minor tweaks or bug-fixes).

    Re: Howto make USB boot drives

    I have tested mkusb in a fairly new laptop with an nvme drive.

    - It is a Lenovo V130 with a Samsung drive
    - Windows was installed with the storage controller mode RST (a setting in a UEFI/BIOS menu)
    - In order for Ubuntu to see the drive I had to change to the storage controller mode AHCI
    - I backed up Windows with Clonezilla

    - I installed persistent live Lubuntu Focal (yes, into the nvme drive, so the persistent live system is really fast).

    It works as it should in this drive. See the attached screenshot.



    Edit: Please notice that you need mkusb version 12.3.8 in order to manage nvme drives.

    |  The real mkusb version 11 was edited last time  2018-03-10 (11.2.2)  |
    |  and it was only cosmetic. The previous edit was 2017-03-28 (11.2.1)  | 
    |  It has been replaced by mkusb version 12 alias dus.                  |
    |                                                                       |
    |  If you are still using version 11, please try version 12, which has  |
    |  been developed with several new features and bugfixes.               |
    |                                                                       |
    |  If you really want to continue using version 11 (mkusb-11), please   |
    |  let me know via a post here in this thread.                          |
