[gentoo-user] uefi gpt grub2

[gentoo-user] uefi gpt grub2

[jdm]

Over the last few days I have tried to set up using uefi gpt and grub2. After many hours of frustration I have gone back to grub legacy and mbr.

I followed the Gentoo wiki  and Arch wiki and several other sources of which I failed miserably. Is this technology fairly unreliable? I booted from a uefi enabled usb stick but still fell over. Is this ready for mainstream or 
 still alpha like?

Also does ufibootmgr change motherboard firmware? Somehow this feels 
wrong if the case.

Hi,

I tried installing UEFI GPT too a few months ago, but I had a semi success.
After some days of fiddeling around with parameters and variables I could
boot the system, but I can't see the kernel output or open-rc. But the X
loads and the system works after that like normal, but without the textual
ttys. terminal emulations like xterm or so work. So I would install it
again, but it isn't as easy as thought.

built-in efifb and add video=efifb to kernel command line.

Thanks for the advise, I'll try it when I'm back at the machine next week

FWIW I hate grub2.  ;)

I'm a big fan syslinux/extlinux.

But recent Linux kernels can be compiled as UEFI apps, thus don't need
a boot loader (e.g. grub2) at all (in theory).

Hmmm agree with the grub2 thing. Seems overly complicated just to get
an OS running. But maybe there are good reasons for it. I'm no expert
understanding boot loaders though.

UEFI apps sounds interesting. I'll have a look into it. But I dual boot
with Windows so maybe forced to use grub2 or such like.

Does syslinux work with uefi/gpt?

Currently, not with uefi MO, it seems. But it works fine with gpt
partitioning on MBR motherboards. Just follow the Arch Linux WiKi. No
reason to submit to the grub2 silliness :)
