One thing to notice is that on the new ISO DISKPART version is 3.0 (so older than the Old ISO Diskpart version ). With the new iso, no problem at all, looking at the same partition with DISKPART brought back 5 possibilities: RESF or NTFS or exFAT or FAT or FAT32 (Youpi !!!!!!).For sure then it is possible to format the EFI partition in FAT32 and everythin runs well. Looking at DISKPART FILESYSTEM for "System" partition with the old ISO brings back only 3 possibilities : RESF or NTFS or exFAT.One thing to notice is that my old ISO is using DiskPart version 8.0 I've done the same procedure as the one proposed by Navy this time without success
