Hope I got this straight, and this is the place to post questions:
Have made a persistent USB of Ubuntu 18.04. Which worked fine until I tried to boot my mac mini (2009) It booted fine for a couple of times then the boot partition got messed up. It won't even boot on a PC now. Here's the error message:
(initramfs) Mount: mounting/cow on/root failed: Invalid argument overlay mount failed.

I put a lot of time into creating and setting this up with apps etc. Is there a way to rectify this? 

Thanks, Charles

mount: mounting /cow on /root failed: invalid argument  is what you typically get if you enabled persistence in Rufus (i.e. you set a persistent partition size that isn't zero) and are working with an ISO where  Ubuntu/casper bug #1489855  has not been patched (which pretty much means every version of Ubuntu except the very latest 19.10).
If you want to use persistence with Ubuntu through a persistent partition that resides on the same media as the one you boot from, you   must   make sure that you use a version of Ubuntu where bug #1489855 has been fixed, which, right now, is only the case when using a  daily-live  ISO of 19.10 released after August 1st. I am not aware of any pre 19.10 ISO that includes the casper bugfix. Especially 18.04.03 will not work with a persistent partition because of the casper bug above.
Otherwise, either make sure that you set the persistent partition size to 0 in Rufus (no persistence) or use DD mode when prompted

If you read the statement… yes.. it says everything… under 19.10… its because of the persistence..
https://askubuntu.com/questions/1176134/couldnt-get-size-0x800000000000000e-when-trying-to-install-ubuntu-18-04-from
claims the .1 release works.. but your using a setup that a very niche set of people use for daily driver usage.. so not much troubleshooting for it
