How can I fix or back up a system after I use gparted to resize my drive and the system will not start?
I was actually able to figure this out myself (no thanks to Apple), but have seen a lot of questions similar, so I thought I would share what worked for me:

I downloaded Gnome Disk for Linux
reformatted the corrupted drive to Apple AFPS
and then remounted the drive

I was able to get everything back and into macOS.
