I am trying to make a bootable LiveUSB backup of my system. After getting into trouble with
Systemback, I am trying
PinguyBuilder. It seems nice, since it is a simple script that can be adapted.
However, I fail to boot from the ISO files it creates. I am suspecting (but I don't know) that the problem is within the creation or burning process of the ISO. My (compressed) system is larger than 4GB. So I hat to tweak
PinguyBuilder a little bit to generate these larger images. Nevertheless I can generate a bootable USB stick based on it.
The error I am encountering occurs when booting from the stick. After choosing from a dialog to boot the LiveUSB, it will show a message that it failed to mount my
squashfs. However, the contained
squashfs mounts just fine on my working system.
I am wondering If I can generate my bootable LiveUSB directly from the files (mostly the
PinguyBuilder generated. It leaves a working directory
boot casper dists EFI install isolinux md5sum.txt pool preseed README.diskdefines ubuntu.
casper subdirectory contains essentials like
vmlinuz. But how can I generate a bootable USB stick from it? Note that I don't necessarily need a tool. I can partition the USB stick and copy files myself, if necessary.
