yes that's correct, when you customize your own partitions like you have done here you should create a small partition just for efi. So go back and create a partition in a size of 256MB and select efi as mount point.

You can read more about recommended partitions here

Your first partition is FAT32 by format, but you must pick EFI System Partition in the "right click→use as…" Dialog. (which of course implies FAT32, but not the other way round)

I had the same issue. Try changing the size of the RAM allocation (SWAP). The size of this partition should be at least equal to the size of system RAM.

first of go into the hard disk drive's /boot/efi folder and rename the file grubx64.efi to mmx64.efi or other formats.

Reboot the machine and it should work.

This time when you are installing create a partition around 256MB and choose primary and EFI system partition. I hope this helps
