UEFI Bootloader didn't show | Dual boot guide don't work

After installation UEFI option didn’t show in boot menu.

I already tried to follow dual boot guide with Windows 10 but after mount partitions and running bootctl code it returns an error saying that partition it’s not FAT32, but gparted confirms that it is FAT32.

Only showing warning for mtools to see some information.

The boot partion has a flag named “msftdata”, maybe it could be the problem, but I don’t know how to safely remove it.

Thank you for helping me, I really want to use this linux distro for programming.
