I would like to create an Ubuntu live usb with persistence. With Linux Tails it was working well for me without problem but for Ubuntu and Mint I have some problems.
I tried to use rufus, unetbootlin and so on from Windows and mkusb from Linux.I always ended up with the following:
I have a casper-rw partition which is not writable after boot by default (after chmod777 it is writeable). When I am booting in grub I never see persistence in the parameter list (on partition 4 - see partition description little later). I tried to add it there but system become unstable and haven't saved any changes I made like it is a live boot.
Last time I used mkusb. It looks that everything went OK (there were no errors in the console). I see new2 boot options in the BIOS.
If I choose the partition 3 than it does nothing, only black screen and nothing happens. If I boot with the partition 4 than I can see a "usbboot" partition as partition 3. On that I see a grub.cfg which looks good, there is persistence and so on in the file.
If I choose the partition 4 for boot than it boots without any persistent (looks like this is the live usb image)
Can you please help me to fix this issue?
Do I have to activate persistence storage somehow like in the TAILS Linux? If you need any further details please let me know.
