Just down loaded the latest daily ISO for Ubuntu, It boots into the live desktop okay.
I run through the installer fine, when it gets to the end of the installation it gives me a fatal Grub error then completes the install with the Continue testing or Restart box

Just to update i rebooted the new install, and I get a grub menu that looks correct, it also has the other partition that is on this computer with KDE neon installed.
Whne booting into the new install it fails with errors. I have attached a screenshot of the boot errors.
Hope this helps.
