Persistent Ubuntu USB drive
Solution 1:
I see you are able to boot into Ubuntu. In that case you could then create a 'persistent ubuntu drive' from the live Ubuntu using instructions here or here.
So you basically have:
- Flash drive 1: Made bootable from OSX. This you are able to boot on your Lenovo (but no persistence)
- Flash drive 2: You want this as your persistent Ubuntu drive.
What you do is:
- Live boot into Flash Drive 1 on your Lenovo.
- Install
mkusbon it. - Use mkusb to turn Flash Drive 2 persistent.
Done.
