Howdy,
I'm installing Gentoo on another old box. To be consistent I like to
use cgdisk, GPT I think it is called, to partition all my drives,
regardless of size. Thing is, Grub works differently with GPT than it
does with the old DOS or whatever it is called, like fdisk does in the
old days. I did some research but still find myself in some muddy
waters. My take on some things I've read, I need a boot partition, not
to be confused with the /boot for kernels, init thingys and such. Where
I get lost, most use gdisk. I like cgdisk. Before that I liked
cfdisk. Anyway, how do I set up that partition with cgdisk? Any
minimum size requirements or tiny is enough? Does it have to be a
specific type? Does it need to be in a specific place? Formatted with
a file system? Also, when I do grub-install, do I still point to
/dev/sda or to /dev/sda1, if sda1 is the special boot partition?
I tried to find a step by step howto with this info but the ones I find
either don't work or leaves me more confused. Given that the method is
also aging out, it's hard to find good guides. I'd be real happy just
to have a link to a good howto that I can make sense of. I can save a
copy local and even print it. Maybe someone has some notes that will
help. I just need something to help clear up the muddy waters.
Hmm ...
Michael's version does not ring any bells with me, and indeed my system
is *not* set up that way. It's UEFI-capable, but at the time I didn't
have a clue what I was doing, so the mobo dumped me into BIOS, and I
just installed everything the old way I knew.
I do, however, have a 512MB partition configured as type "Microsoft
basic data". This is meant to be for the UEFI partition if I get round
to converting the system.
If you want to "suck it and see", just install grub to /dev/sda. All
your GPT disks, by default, leave the first 2MB empty, and grub will
stick itself in there I believe.
