if i had the same issue on my acer craptop but is a old thing i would try https://bugs.archlinux.org/task/34641#comment111365
is far fetched (does it called that?) because of the memory space in efi stuf with efi_no_storage_paronoia does not check it… if you set E you can edit the kernel line… i dont know…its a pain to emulate this issue
so can’t tell if you have this issue before , installing without grub is a good thig but have to devine in lol
