![]() Type command ls to see available devices. You should see the grub> prompt.įirst, check if GRUB detects your USB drive. When the GRUB screen appear, press C or ESC to go to the GRUB console. If you have your bootable USB drive, insert it into the computer. If not, you can use a tool called Unetbootin to create a bootable USB drive. I assume that you already have a bootable USB drive with your favorite Linux distro. I had an opportunity to learn how to boot from USB using GRUB. Moreover, ever since I installed GRUB, the shortcut to summon booting device selection stopped working. I prepared a USB stick with the new system, but I couldn’t boot from it – BIOS was restoring the booting order on every reboot. ![]() I use it from time to time, but one day the filesystem crashed, and even fsck couldn’t repair it. One of my old computers runs Linux with GRUB as a bootloader. But what if both options failed for some reason? If not, there is an option in BIOS/UEFI to change that. ![]() So you might as well let it sort your issue for you, by using it with an ISO that actually has a chance to work.Almost every modern computer has a dedicated menu to choose from which device the system should boot. I spent a lot of time ensuring that Rufus can automate the hard work for you (again, provided that the distro you use isn't plagued with a major bug with regards to persistent partition support), and you indicated that you tested Rufus. Wait until the Mint distro maintainers pick the casper fix and produce a release that is not plagued by bug #1489855 and can therefore properly support persistent partitions.For instance, there again, Debian Live 10.x should work just fine for persistence with Rufus 3.8 or later. Use Debian or a Debian derivative that doesn't use casper-rw for persistence.Unetbootin linux is a great program that allows you to create bootable live USB drives for Ubuntu, Fedora, and other Linux distributions without burning a CD. After the installation is complete, restart the computer. It should work just fine for persistence (source: I am the developer of Rufus, and I have tested it fairly extensively to make sure that it does work). For Windows users, the Unetbootin utility can be used to access the Windows boot menu. Download the latest daily-live of Ubuntu 19.10 and use that with Rufus 3.8 or later.At this stage, I'm not aware of any distro having backported the fix for #1489855 into an updated release. And I'm afraid that, since Mint is a derivative of Ubuntu, it suffers from the same casper bug. If you use a casper-rw persistent partition on the same drive you're booting from with anything but (the yet to be released) Ubuntu 19.10, you're going to be screwed because of Ubuntu/casper bug #1489855. Starting with Ubuntu 19.10, persistent partitions can be added to UNetbootin and Rufus and also to cloned drives. (where count=512 is persistence size, with max size = 4GB). To create a casper-rw file: sudo dd if=/dev/zero of=casper-rw bs=1M count=512 Mkusb Live installs also use ISO9660 file system, (which GParted won't modify), however mkusb can be downloaded to the Live USB and used to turn the Live USB into an excellent Persistent drive that uses casper-rw partitions of unlimited size. Start up Disk Creator uses a write only ISO9660 file system which takes up the whole drive and GParted can't modify. Edit /isolinux/txt.cfg, (for BIOS boot persistence) and /boot/grub/grub.cfg, (for UEFI boot persistence), thus: ".splash - persistent". Edit syslinux.cfg, adding a space and the word persistent to default boot, thus: ".splash - persistent". UNetbootin: Add casper-rw file to USB root. If you need any further details please let me know. If I choose the partition 4 for boot than it boots without any persistent (looks like this is the live usb image)Ĭan you please help me to fix this issue?ĭo I have to activate persistence storage somehow like in the TAILS Linux? On that I see a grub.cfg which looks good, there is persistence and so on in the file. If I boot with the partition 4 than I can see a "usbboot" partition as partition 3. If I choose the partition 3 than it does nothing, only black screen and nothing happens. It looks that everything went OK (there were no errors in the console). I tried to add it there but system become unstable and haven't saved any changes I made like it is a live boot. When I am booting in grub I never see persistence in the parameter list (on partition 4 - see partition description little later). I have a casper-rw partition which is not writable after boot by default (after chmod777 it is writeable). I tried to use rufus, unetbootlin and so on from Windows and mkusb from Linux.I always ended up with the following: ![]() With Linux Tails it was working well for me without problem but for Ubuntu and Mint I have some problems. I would like to create an Ubuntu live usb with persistence.
