Void grub install unbootable on some motherboards

[T3cube]

The MSI z170a SLI plus motherboard will not recognize grub unless some files (I don't know what files specifically) are found in /boot. It ignores files in /boot/EFI for some reason. (Worked around this in Arch Linux by installing grub to /boot and it picked it up just fine)

Allow the installer to install grub to other directories instead of only /boot/efi

Fresh install of debian 13 works just fine

I can try and provide more information if needed, I am no expert unfortunately.

it supports UEFI boot. bios boot has the same issue. thats allot of work for fixing an iso installer that should be bootable after install. my system is running debian and i have no reason to redo the install.

the iso boots, it installs, and then the install doesnt boot. grub just isnt found
