Artifacts left behind..

incomplete grub-install .. fixed with via a chroot -> grub-install --target i386-pc /dev/sda

Reference to usbstick efi partition in fstab prevents boot .. fixed commented out in /etc/fstab

then normal boot proceeds .. everything else appears normal

fix only present if auto resize is used .. will still fail with manual resizing.

Auto resize adds a EFI fat32 partition during the resize. this prevents the grub install failure.

if an EFI partition is not present the installer will fail ..

confirmed that manual partition selection install without EFI fat32 partition present will fail on grub install .. due to install media EFI fat32 partition being substituted into new install fstab ..

So why does ubiquity not recognize that it is installing on an mbr partitioned disk? and adjust accordingly.. seems rather wrong that the install all fails at the install of grub .. especially as everything else is ok..

also stealing 500 MB for an efi partition when it is not needed is rather a waste
