I've installed a new motherboard into my server (SuperMicro X9DRi-F) and I'm trying to install a fresh copy of Debian 10. However, when it tries to install GRUB it fails:
Unable to install GRUB in dummy Executing 'grub-install dummy' failed. This is a fatal error.
I'm making sure to boot the installer (USB drive) in UEFI mode because I'm entering the BIOS and forcing it to boot (which correctly displays "UEFI: Sandisk").
I can't cut and paste the /var/log/syslog message but here is basically what it says:
Installing grub on 'dummy' grub-install does not support --no-floppy Running chroot /target grub-install --force "dummy" Installing for x86_64-efi platform. grub-install: warning: Cannot read EFI Boot* variables. grub-install: warning: read_file: could not read from file: Input/output error. grub-install: warning: vars_get_variable: read_file(...) failed: Input/output error.
I've searched and I see others with this problem but it's not clear how anybody has solved it?
Can anybody help me out?
