background information ( It doesn’t matter )
current i have trying to reinstall ubuntu in my dual system computer (ubuntu, nixos), after installed, the nixos bootloader has disappear, only ubuntu’s existed. The boot just like this, after serise of operation base on guildline and wiki, it magically reinstall bootloader successed.
Information about current situation
But after the leading authority of bootloader have been change from Ubuntu into NixOS, the item inside the file under the /boot/efi/EFI/ubuntu{BOOTX64, grubx64.efi, mmx64.efi, shimx64.efi}
has been change into binary, ** isn’t means that this file has been control by NixOS? What should I do to change this file, for example GRUB_TIMEOUT_STYLE
and GRUB_TIMEOUT
** ?
I have checked all options under boot.loader.systemd-boot
, but it seems to haven’t any help.
Configuration file right now
boot.loader = {
systemd-boot = {
enable = true;
extraEntries = {
"UkyinUbuntu.conf" = ''
title UkyinUbuntu
efi /efi/ubuntu/shimx64.efi
'';
};
};
efi.canTouchEfiVariables = true;
efi.efiSysMountPoint = "/boot/efi";
};
