[gentoo-user] switching from "refine" to "grub"

[gentoo-user] switching from "refine" to "grub"

[thelma]

I use refine as boot loader but it is giving me a problems.
How to switch back to grub 2
And remove any refine files from /boot

I can not say for certain, but I imagine it would be something like this:

emerge -c refine
rm  -rf  <EFI_DIR>
rm -rf /boot/refine
GRUB_TARGET="x86_64-efi" emerge grub
grub-install --efi-directory=<EFI_DIR> --target=x86_64-efi
grub-mkconfig -o /boot/grub/grub.cfg


Of course you really should put the GRUB_TARGET in your make.conf, but 
in a pinch that will work. I'm assuming you are using a 64-bit EFI 
enabled computer. The grub steps I am sure of. I've never used refine 
before, so I don't know it.

I take it you mean refind? It may well be easier to solve the problem
with refind rather than trying to deal with the overcomplexity of GRUB
for an EFI system.

I normally use systemd-boot but when I have used refind, it has picked up
everything it needs to know without a config file. What errors are you
seeing?

What complexity? I have a couple EFI machines booting via Grub, and they 
work great. I just had to ensure the correct GRUB_TARGET in make.conf 
and then after I had my partitions setup and formatted, I just did 
grub-install --target=x86_64-efi --efi-directory=/boot/EFI and it went 
smooth as silk as long as I didn't have /boot on newer ZFS setup. Even 
ZFS would work if you setup /boot to be a separate dataset and make it 
with absolute minimal options.

GRUB2 is hugely complex as it tries to be everything to everyone. That's
not a bad thing in itself, but EFI can use a far more minimal setup.

I didn't say it didn't work, but it is overkill for EFI booting where a
bootloader isn't needed.
