Your EFI system partition is corrupt; you will need to repair it with either dosfsck or Windows' chkdsk/scandisk.

Changed in grub-installer (Ubuntu):

The solution was manually partitioning the disk and choosing the installation location of grub to an efi partition. I guess ubuntu was trying to install the grub to a wrong partition, such as /dev/sda.
