How to make a persistent live Ubuntu USB Memory stick (16GB)
|16Gb Flash disk|
I wanted to create a boo-table Ubuntu live flash stick that will also keep my last installed applications and not default back to standard when I reboot.
|Ubuntu 17.10 Live with all my apps|
You need to create two partition fat32 for the Ubuntu instillation from ISO file and a ext4 casper-rw partition for the persistent part. The compleet proses is done with a application called DUS.
Here is the process to install the DUS software
sudo add-apt-repository universe
sudo add-apt-repository ppa:mkusb/ppa
sudo apt-get update
sudo apt-get install mkusb usb-pack-efi
sudo apt-get install mkusb-nox usb-pack-efi
Select the following on the screens.
1) Double-Click on the i option Install(make a boot device):
2) Double-Click on the p option Persistent Live and select the .iso file:
3) Click on the USB drive to make persistent. I want to use my 32 GB one so I mark the radio button:
4) Click Use Defaults to let
5) Enter a percentage of the drive to reserve for persistence. Mine is a large (32GB) so I allot only 20% ~ 6GB. The remaining space will be turned into an empty portable drive:
6) Double check very carefully and confirm. You don't want to mess up another drive.
Waite until 'Done' is written go and get some coffie :-)
Here was my configuration
Cruzer Blade sdb 14.6G
|-sdb4 iso9660 Ubuntu 17.10 amd64 1.4G
|-sdb5 ext4 casper-rw 12.9G
|-sdb3 vfat usbboot 244M
