[gentoo-user] UEFI boot, again

[gentoo-user] UEFI boot, again

[Stefan G. Weichinger]

Greets,

could someone please show me the exact content of his
EFI-boot-partition, especially the stuff for gentoo?

Yesterday my main SSD crashed, the support of company XXX told me to
erase the CMOS of the board ... zap .. that were my EFI-settings ... and
the EFI-boot-partition is on the SSD  .... I was able to recover it but
somehow I don't get it right ...

all that /boot/efi /boot/efi/EFI bla ... and all the howtos I google
slightly differ and I just can't make it work right now.

I want to boot a gentoo-installation on /dev/md3 ... no separate /boot.
The EFI-boot-partition is /dev/sda5.

Pls point me at some working instructions ... I tend to use EFI as I
have both hdds partitioned with GPT.

Right now I boot using a USB-stick and manually pointing at the grub.cfg
from there ... *sigh*

Thanks in advance, Stefan

ps: I am a bit ill and rather overworked, this might make understanding
harder this time ;)

I am currently fighting this on a macbook air ... efi is crap, at least
the old grub was much easier to fix when it went wrong ...

if you are using grub 2  (I tried refit/refind/grub2/efi kernel and
finally settled on grub2)

try:
mount /boot
mount /boot/efi
`grub2-install --target=x86_64-efi`
`grub2-mkconfig -o /boot/efi/EFI/gentoo/grub.conf`
# have to sort this out one day, which is it using?
`cp /boot/efi/EFI/gentoo/grub.conf /boot/grub2/grub.cfg`

Sounds like your install line is what you are missing ...

Thanks a lot, Bill, I will look into this later this day.

What do mean by "install line" ?

So you have a /boot and a /boot/efi partition. Hmm.

My /boot is just a sub-directory on /dev/md3 ... might make a difference
at boot-time.

I had EFI stuff working already but with both /root and /boot on plain
partitions on the SSD, without any underlying raid.

(this SSD started getting flaky lately, leading to all this)

I might try setting up a separate /boot now, GPT allows many partitions
anyway ;-)

The grub2-install command above - with efi you have to "announce" the
the information to boot with.  I look at it as similar to grub
installing into the MBR, but thats a very loose metaphor :)

The problem you are describing might be that this "announcement" is
missing/corrupted.

The EFI directory is Apples (this is a macbook air), the grub2-mkconfig
searches for all the bootable kernels and builds a menu for them.  I
think this is close to default efi in layout as "EFI" seems to be in the
spec.

When I boot, it tells me that the disk isn't bootable.

The usb-stick is, it gives me a grub-cli and I pull my configfile from
there.

Maybe I have to re-enable EFI for the hard-disk in the BIOS??

But I get entries like GRUB2 in my boot menu (BIOS-level).

I am somehow losing track here already and I get the feeling that even
if I get things working I won't really be knowing how I got there ;-)

Re: [gentoo-user] UEFI boot, again

[Stefan G. Weichinger]

oh, what joy.

I now have the box booting via EFI, from the USB-stick, with my grub.cfg
on there ... a step forward at least.

Kind of a security feature ;-)

Update: no such feature there.
See other mail, booting from stick now ;-)

More on this later today, got to do something else now.

another "feature" is you have to be booted via efi so the variables are
available so it can install itself - sorta catch 22 :(

I just remembered another step that I missed - I dont have the syntax
but "efibootmgr" - google for the correct options.

Yes, I know that. No problem, when I boot from that stick, I do that via
EFI, so I get the correct environment.

Yes ;-)

I do that for days now. What puzzles me:

I get the entries into EFI: when I boot I see the entries created by
efibootmgr, but when I chose one of the entries pointing to "GRUB2" or
"gentoo" the PC tells me that the disk isn't bootable.

And I still don't know what is missing. AFAIK that EFI system partition
is allowed to be within the first 2 TB of the disk (easy on my 1 TB
hdd), has to have the boot-flag set (in parted-terms), and must be type
EF02. When EFI doesn't find something bootable on the disk, my
interpretation is that it can't find that partition?

Maybe the boot entry in the EFI firmware is wrong. That's what mine
looks like:

# efibootmgr -v

Do an "ls" from the grub prompt ... when booted from the usb stick grub
will renumber the devices in a different order.  You will need to use
"ls" to find out what the current grub order is, edit the grub menu
(i.e., "e" when at the menu selection) and press F10 (I think) when done
to boot.  The reason is grub will set itself up with the usbstick as
root, whereas once you boot with the correct mapping you can reissue the
commands to write them properly.

Looks good, could you cross-check if the GUID is correct? My EFI
partition is the first one on my ssd, so I use #  sgdisk -i1 /dev/sda to
check. The value you are looking for is "Partition unique GUID" - should
be the same to what efibootmgr displays

That is the ID of /dev/sda5:

 # sgdisk -i5 /dev/sda
Partition GUID code: C12A7328-F81F-11D2-BA4B-00A0C93EC93B (EFI System)
Partition unique GUID: 0C67029A-25DE-4E23-B2BE-6C502742189E
First sector: 1296046080 (at 618.0 GiB)
Last sector: 1296455679 (at 618.2 GiB)
Partition size: 409600 sectors (200.0 MiB)
Attribute flags: 0000000000000000
Partition name: 'EFI System'

This is the EFI-system-partition on /dev/sda.
Should it point there?

In my case sda1 is a Linux RAID partition, which is part of md0, which
once was my / (too small now).

What I tried to achieve:

sda5: EFI system ( -> /boot/efi )

gentoo-root on /dev/md3 (consists of sda6 and sdb3)

I know this looks like a mess, and somehow it is.

But right now I see something else:

Boot0000* GRUB2
HD(5,4d401800,64000,0c67029a-25de-4e23-b2be-6c502742189e)File(\EFI\GRUB2\grubx64.efi)

would point at my /dev/sda5 and the file \EFI\GRUB2\grubx64.efi in
there, right?

After all my fiddling around right now it is named

/boot/efi/EFI/grub2/grubx64.efi

case-sensitive? Vfat ... ? I just rename it and give it a try ;-)

What about that ugly Boot0007 in my listing?

Yes, correct. Everything so far looks okay to me. So when you book in
EFI mode you should get at least a grub shell - even if your grub.cfg is
missing or incorrect. But on the other hand, UEFI is a bitch, took me
several days in trial and error to get it running when I first tested it
(this was with unstable grub then, I even hat to create my own grub
image with grub2-mkimage)

vfat is not case sensitive, so this should be no problem.

Maybe some internal rescue partition or something like that. Looks
strange to me too.

I gave up for now. Re-added SSD, MBR-partitioned.

The BIOS in the HP Elite 7300 only boots via BIOS if there is at least
one disk MBR-partitioned in there (with active boot-flag, I assume).

This EFI-stuff has to wait for times when I have more energy for this, I
got work to do as well ;-)

Thanks all, Stefan
