i need to do this because i want to start any machine with this usb drive, i thought with that direct installation, you can not start any machine becasue of the driver problems and everything. please correct me if i m wrong??? but here is the solution that i came up with anyway...
- i created a casper-rw partition seperate from home-rw partition.
- installed ubuntu live usb through unetbootin, after installation finished,
- edit the syslinux.cfg file from different OS because if you start it from the live usb you just created you can't overwrite that file.
- then starte it regularly from usb and when unetbootin screen comes and showing options press tab at Default and at the end of the code add persistent starting with space.
this worked for me. everything that i make even the settings stays the same, packages stays everything stays it is amazing.
what i m trying to do basically is by using unetbootin in the same flash drive have two things
1- persistent ubuntu
2- (not persistent) Backtrack Live
so in seperate partitions in the usb drive i individually created live Backtrack first then the Persistent Ubuntu.
If anybody knows a better of creating both OSs with given specifications in the same usb flash drive, please do let me know.
I know you can have many Live cd s in the same usb but i needed ubuntu persistent and actually work as persistent.
this was the solution that worked for me.
and jefro thank you for your response...
