Get a USB drive and burn SuperGrubDisk to it. It's a utility that detects GRUB and lets you boot into the system if there is any problem. Start from here, try to boot into your ubuntu and then try to reinstall and debug.

Make sure you have latest UEFI from Acer. Some older threads mention downgrading UEFI, but newer threads say newest works.
And Acer has an unique requirement of inside UEFI setting a supervisory password and then enabling "trust" on the ubuntu/grub .efi boot file in the ESP.
