Still learning...
Okay - I know for sure that I edited the grub.cfg file from boot/efi/EFI/ubuntu as it was the one that had the wrong UUID - and where I have a backup... Looking at the grub.cfg file in boot/efi/EFI/robolinux it is now identical to the corrected one in boot/efi/EFI/ubuntu (that makes sense...)
Pretty sure that the Robolinux did a standard UEFI install.
I am sure - that even now I can not boot my Android X86 install normally. I still have to hit esc/F9 and choose the Android EFI file to boot. I'd love to clean that up (and learn how)
There is no grub.cfg inside boot/efi/EFI/Android. There are 3 .efi files: bootia32.efi, BOOTx64.efi and grubx64.efi. I don't know how to read inside those files as they don't open in a text editor...
There is one more file - Android.cfg. It seems "grub-ish" :
The grub file that is booting is definitely the Robolinux one and looks like this:Code:# $1 Kernel dir # $2 Title # $3... Kernel cmdline function add_boot_entry { menuentry "$2" "$@" --class android-x86 { savedefault set root=$android if [ -e $2/kernel ]; then true else search --no-floppy --set root -f $2/kernel fi set kd=$2 shift 3 linux $kd/kernel root=/dev/ram0 androidboot.selinux=permissive $src $@ initrd $kd/initrd.img } } # $1 Title # $2...

Working in Grub Customizer to see if I can get it to make it boot but this is what I have so far.
Thanks again for all of the help!
