Switch from casper-rw file to casper-rw partition

I am running Ubuntu 16.04 in 16 GB USB drive. I am a newbie in the ubuntu world. I am trying to create a USB disk with 12 GB persistence storage. So that I can use it for the development purposes.
I have created this USB drive using
unetbootin
. I have selected100 MB
persistence while creating the disk, because I wanted to switch tocasper-rw
ext2 partition which I created and having12 GB
space. But, even after restarting and booting to windows and live-ubuntu more than 20 times with different settings and juggling between different tools, still unable to get that partition working.I have tried
rufus
,unetbootin
, andlinuxpendrive
tools for making persistent file storage system. But to enable partition, I have failed all the time. If I change thetxt.cfg
file from my windows, it ends up in Busybox dead screen without any error.First, I partitioned my usb storage to 2 drives from windows 10 using EaseUS Partition Manager. 1
fat32
of2 GB
and 1ext2
withcasper-rw
label. Then Installed ubuntu using unetbootin with persistance settings to 100 MB. It works but doesn't use partition for persistence. When I check from the command:df . -h
, it says I have /cow with 100 MB space. I tried to delete the filecasper-rw
from USB drive from fat32 partition from Windows and again booted from USB. But, it fails to boot and stuck to BusyBox Screen.One article I followed: https://askubuntu.com/a/438734/588390
I tried:
As rufus doesn't provide direct option to enable persistence, I tried enabling it with linuxpendrive's Casper-RW creator tool (http://www.pendrivelinux.com/casper-rw-creator-make-a-persistent-file-from-windows/). Then deleted and/or renamed
casper-rw
file in the root usb. But didn't worked.Tried editing
txt.cfg
file and it ended up in dead Busybox screen with all the 3 tools.I also tried editing one cfg file inside
boot/grub
but also ended up in the Black Busybox dead screen.
What's going wrong?
Thanks.

Anwar over 7 yearsYou said " I have selected 100 MB persistence while creating the disk, because I wanted to switch to casper-rw ext2 partition which I created and having 12 GB space. " What is the difference between this 100 MB persistence and your 12GB casper-rw file?

kirtan403 over 7 yearsBecause, It was mentioned in many articles that first create with casper-rw file and then delete that file so it will use the casper-rw partition

JamesBB over 7 yearsYou need to repoint your boot-loader menu (grub) to the new partition. (this is the advice that is generally not pointed out on casper-partition answers!) I managed to get this working recently with a Lubuntu 14.04 custom iso as described here (http://askubuntu.com/a/878009/544376). that's my answer to someone else's question where he was having a similar issue. My answer used other answers on that 'thread', so be sure to read the entire thread before you try again. Good luck!
