I've been through numerous sites/forums/how-to's and still am baffled. What is causing the problem, I believe, is the casper-rw partition not being recognized at bootup. I have looked at few posts here and must say, it's rather confusing. So, what must be done to make the casper-rw partition be recognized at bootup? And, I still have to delete the casper-rw file in the O.S.? Running Xubuntu 18.3 live--2GB partition for O.S. and 1 GB for casper-rw(ext2) on a 16GB Lexar 2.0 pendrive. The link listed below gives a fairly accurate description of my problem:

Unable to boot Ubuntu Live USB Flash Drive with casper-rw persistent partition

  • Currently syslinux type installers like UNetbootin, Rufus, Universal and Startup Disk Creator do not allow a persistent partition on the same drive, a persistent partition works OK as long as it is on a different drive. – C.S.Cameron Jul 12 '18 at 0:13

Currently syslinux type installers like UNetbootin, Rufus, Universal and Startup Disk Creator do not allow a persistent partition on the same drive, a persistent partition works OK as long as it is on a different drive.

YUMI can create multiple persistence files for multiple OS and uses grub4dos to make casper-rw files greater than 4GB.

Persistent partitions work great if used on a grub2 type persistent drive such as mkusb creates.

mkusb will create a flash drive with FAT boot partition, ISO9660 OS partition, ext2 casper-rw persistence partition and a NTFS data partition accessible to Linux and Windows. https://help.ubuntu.com/community/mkusb

Download mkusb to a ubuntu boot drive and use it to make your persistent drive.
