What brand/model system. Some require work arounds. But you are showing grub entry, not typical Ubuntu entry. If not from another install like Debian, grub is not correct. I installed 18.10 and got a similar grub entry, but it used my default /EFI/ubuntu/grub.cfg file, not the /EFI/grub/grub.cfg file for 18.10. You do not have /EFI/ubuntu folder in ESP? If not copy all of /EFI/grub to /EFI/ubuntu. You may only need grub.cfg for it to work.

Set your boot mode to UEFI, if it doesn't work, try install again with UEFI and be sure to set the partition to GPT rather than MBR to avoid these kind of things!

I had same issue. Solved by manual partitioning of hard disk within installer.
I chose partition1 /dev/sda1 type efi size 1023 type boot. Partition 2 type swap size 2xRAM e.g 16384. Partition 3 ext4 / remaining. But i believe wher it all ends in tears is that one needs to select at bottom of screen boot=/dev/sda1 NOT boot=/dev/sda

I'm having a similar problem: after installing Ubuntu I was left with an empty grub prompt.
I'm dual booting with Windows 10. Both the ssd on which I have the Windows and the EFI partition, and the harddisk on which I have Ubuntu are partitioned with GPT. Bios is set to boot in UEFI mode, with secure boot and fast boot both turned off.
I've installed grub-efi-amd64, but it changed nothing.
After installing Ubuntu, I could boot either operating system only by pressing F12 to access the boot menu, from where I could choose either Windows or Ubuntu, both of which continue booting normally from here, the Ubuntu menu entry leading to a working grub.
At the end, I've had to edit my EFI entries so that Windows would be the first one, so that at least now Windows loads directly, without any further intervention during the boot process. If I want to enter Ubuntu, I have to go through the bios boot menu.

I had same issue. Solved by manual partitioning of hard disk within installer.
I chose partition1 /dev/sda1 type efi size 1023 type boot. Partition 2 type swap size 2xRAM e.g 16384. Partition 3 ext4 / remaining. But i believe wher it all ends in tears is that one needs to select at bottom of screen boot=/dev/sda1 NOT boot=/dev/sda

I'm having a similar problem: after installing Ubuntu I was left with an empty grub prompt.
I'm dual booting with Windows 10. Both the ssd on which I have the Windows and the EFI partition, and the harddisk on which I have Ubuntu are partitioned with GPT. Bios is set to boot in UEFI mode, with secure boot and fast boot both turned off.
I've installed grub-efi-amd64, but it changed nothing.
After installing Ubuntu, I could boot either operating system only by pressing F12 to access the boot menu, from where I could choose either Windows or Ubuntu, both of which continue booting normally from here, the Ubuntu menu entry leading to a working grub.
At the end, I've had to edit my EFI entries so that Windows would be the first one, so that at least now Windows loads directly, without any further intervention during the boot process. If I want to enter Ubuntu, I have to go through the bios boot menu.

I fixed it by setting BIOS parameter "UEFI/Legacy Boot" to "UEFI Only" and "CSM Support" to Yes.

What brand/model system. Some require work arounds. But you are showing grub entry, not typical Ubuntu entry. If not from another install like Debian, grub is not correct. I installed 18.10 and got a similar grub entry, but it used my default /EFI/ubuntu/grub.cfg file, not the /EFI/grub/grub.cfg file for 18.10. You do not have /EFI/ubuntu folder in ESP? If not copy all of /EFI/grub to /EFI/ubuntu. You may only need grub.cfg for it to work. Please post this bug, if grub UEFI entry is from Ubuntu, not another install: bugs.launchpad.net/ubuntu/+source/grub2/+bug/1775743

@oldfred - custom build, had no /EFI/ubuntu/grub.cfg ( paste.ubuntu.com/p/82bFbST6xw ). That ticket mentioned grub-efi-amd64 was missing and sure enough installing it fixes my issue! Thanks.
