NMGLUGers, We have a meeting scheduled for tonight:
I can relate a little about rescuing a dual boot Ubuntu install where it was a simple matter of BIOS adjustment to allow a usb boot and resizing the partitions which were already in place, but not assigned correctly. Then to reset the BIOS to Legacy to boot the system as installed.
I hope others have some stories or reports of activity with GNU/Linux.
Thank you, Ted P.
