Finally available, I downloaded the latest 24.04 LTS Desktop ISO and tried to install it on a test machine. I always choose to manually partition the drive, so I can create separate partitions for the EFI System Partition (ESP), Root (/) and Home (/home). No matter what i choose, the EFI option is not available under the Partition Type in the partition creation window. I tried to manually mount a VFAT partition under /boot/efi, but as soon as I create the first partition, of any type, it automatically creates a 1.13 GB EFI partition as the second partition. I understand this is normal since the 23.10 installer. It's really annoying, an EFI partition should be 100 MB minimum, or typically 512 MB in size. All my tests were done on the same machine, with a 256 NVMe SSD.

Is there a way to manually create it as in the previous LTS (22.04)?

This is so annoying, I know! I tried even to create the partitions separately but still will fail to use it as boot/efi. But, I found a way!!!

From the installer, just create on an empty partition table (disk) a single partition (full size) for / (root) the installer will automatically create an empty FAT32 for /boot/efi

... after which you can delete the root partition and do as you wish with the rest. This is so counter intuitive!

Make the partition, add the esp and boot flags, and format it before you start the 24.04 installation. If you don't, you find the manual part will not have the critical things like selecting FAT for a fs, EFI for usage, etc.

First of all: The 1.13 Gb is the reserved area, perhaps you will miss the 512 Mb, but 1.13 is an affordable storage.

I selected the manual installation, then when I created a new partition table, I create a full storage / partition; the installer created the boot/efi partition with 1.13 Gb and the rest of space for /. Then I proceed to delete the / partition and create the swap, home and / partitions with the space I required.
