debian-wheezy-amd64-efi-test4.iso doesn't want to install on a Asus 1015BX

Hi,

I can run the installer mode efi but the installation hangs during installation of grub at 50% : 
running "grub-install dummy" ...


At this stage I am obliged to cut the electricity because the netbook does not respond at all, including "Magic SysRq key" :/

Thanks

Best regards,
