Well I worked around the problem using by force util-linux from mga2 in rescue mode. So some notes here about installer, in my case legacy grub1 was not usuable so I used grub2 + efi. Two things are need: - detect the fat32 partition containing EFI/ directory if any or create it, copy on it the grub2-efi boot code (done %post of grub2) - enabling the grub2 boot code, this step is also done in %post fo grub2-efi but it doesn't work in rescue mode because 'efivars' kernel module is not load Once this is done the grub2 configuration is perfectly updated when I install a new kernel. I can boot windows or mageia by setting the boot order in UEFI. Regards. -- Olivier Thauvin CNRS - LATMOS ♖ ♘ ♗ ♕ ♔ ♗ ♘ ♖
