oui car le mode EFi ne fonctionne pas décidément. C'est franchement pénible ! Je suis "on ready" si tu as un code, je suis preneur

Assistant Boot Camp préparera systématiquement une partition temporaire en FAT32 avant de laisser la main à l'installateur de Windows qui demandera par la suite que cette partition temporaire en FAT32 soit formatée en NTFS. Le problème est que vous êtes nombreux à vouloir jouer à l'apprenti sorcier sans tenir compte des impératifs d'Assistant Boot Camp qui doit entre autres créer dans le système la gestion du boot de démarrage de macOS, de Windows, voire d'une partition Linux

GPT fdisk (gdisk) version 1.0.3
Warning: Devices opened with shared lock will not have their
partition table automatically reloaded!
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
Command (? for help): r
Recovery/transformation command (? for help): h
WARNING! Hybrid MBRs are flaky and dangerous! If you decide not to use one,
just hit the Enter key at the below prompt and your MBR partition table will
be untouched.
Type from one to three GPT partition numbers, separated by spaces, to be
added to the hybrid MBR, in sequence: 4
Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): y
Creating entry for GPT partition #4 (MBR partition #2)
Enter an MBR hex code (default 07): 07
Set the bootable flag? (Y/N): y
Warning! GPT partition 4 ends after the 2^32 sector mark! The partition
begins before this point, and is smaller than 2^32 sectors. This is technically
legal, but will confuse some OSes. The partition IS being added to the MBR, but
if your OS misbehaves or can't see the partition, the partition may simply be
unusable in that OS and may need to be resized or omitted from the MBR.
Unused partition space(s) found. Use one to protect more partitions? (Y/N): n
Recovery/transformation command (? for help): w
Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!
Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT) to /dev/disk0.
Warning: Devices opened with shared lock will not have their
partition table automatically reloaded!
Warning: The kernel may continue to use old or deleted partitions.
You should reboot or remove the drive.
The operation has completed successfully.

Tu peux très bien installer la dernière version de Windows 10 dont le nom exact du fichier .iso est Win10_1803_French_x64.iso sans avoir de clé d'activation. L'installation complète se fera, mais limitera certaines fonctionnalités de Windows tant que l'activation ne sera pas faite. J'ai aussi le sentiment que ton problème provient bien de l'installation d'une version antérieure à Windows 10.je peux tenter de réinstaller l'un de ces trois avant de voir repasser à la caisse pour payer win 10 ?
