does the mobo have secure boot on?

modern cradle
#

shouldn't be let me check

#

there is no option for secure boot in bios

#

lol

#

thats why

pulsar lark
#

it's bios?

modern cradle
#

yeah

pulsar lark
#

not UEFI?

modern cradle
#

it is uefi

#

but can't seem to disable secure boot

#

asus pbz68 v pro

#

check

pulsar lark
#

hold on, let check that board

modern cradle
#

see

#

same bios

pulsar lark
#

that explains it, it's an older board

#

hmm

modern cradle
#

yeah

#

its my server

#

lol

#

maybe bios update?

#

3603 current bios

pulsar lark
#

no shade lol, just accustomed to newer boards having those features, don't get me started, I was tinkering with computers in the era of BIOS, dual booting is hard now, then it was worse

#

you shouldn't have to, specially if that board doesn't have fall back UEFI

#

which with the other lacking features, it's probably missing

#

let me look at some stuff real quick

modern cradle
#

i guess it wont boot even in legacy mode if secure boot can't be disabled?

pulsar lark
#

legacy should disable it though

modern cradle
#

so reinstall under mbr legacy

#

no other way?

pulsar lark
#

This is old but it is for grub2

#

which is the new grub

[Request] P8Z68 V-PRO(not Gen3)-modded BIOS with updated oproms

Hello. I’ve been searching for a long time how to switch from Legacy to UEFI mode on this board, whenever I try it, it always halts at logo screen, nothing happens, so I’ve read on multiple forums that I need a modded updated BIOS for the board, but just can’t find it anywhere, only for Gen3 which I suppose isn’t compatible with non-Gen3. Is the...

#

what about this

#

lol

pulsar lark
#

it's a risk but hey it's a server, swappable ebay components amirite

modern cradle
#

no way to run arch with secure boot?

pulsar lark
#

you can

#

the wiki explains that too

modern cradle
#

aha

pulsar lark
#

.aw secure boot

modern cradle
#

that ll work so

dark hollyBOT
modern cradle
#

?

pulsar lark
#

should be section 3

modern cradle
#

i mean it should work

#

it detects win10 and its uefi

#

so

#

its just that this uefi mode can only keep secure boot enabled

#

this is a pain

#

in the aaaaaaaaaaaaaaa

#

lol

pulsar lark
#

win10 doesn't require secure boot is my understanding

modern cradle
#

.aw pain

dark hollyBOT
modern cradle
#

huh

#

but it runs with also

pulsar lark
#

computers that were not compatible with secure boot can't upgrade to Win11

modern cradle
#

thats why its showing

#

u can bypass that

#

but yeh

#

my main pc has a i5 11400f

#

decent enough for me now

#

so

#

i did read

#

you can't boot into windows with the signed personal key

#

It is usually not possible to boot Windows by signing its bootloader (EFI/Microsoft/Boot/bootmgfw.efi) with a custom, personal key with Secure Boot Mode enabled, without enrolling the "Microsoft Windows Production PCA 2011" key in the UEFI Secure Boot variables:

pulsar lark
#

welcome to proprietary shenanigans

modern cradle
#

i ll still be able to boot into it without grub

#

good enough for me

pulsar lark
#

as long as the mobo sees the boot entry you're always good

modern cradle
#

yeah

#

thats the issue

#

lol..

pulsar lark
#

in the server does efibootmgr show you an entry for it?

#

I will guess no

modern cradle
#

can i just setup the secure boot from the arch install with laptop

pulsar lark
#

that is outside of my linux knowledge by miles

#

odds are no, my understanding of secure boot is that it's tied to the hardware

modern cradle
#

i can also boot into it with secure boot enabled from laptop

#

so should be ok

#

just sign the boot files

#

i guess

pulsar lark
#

you can try that if you want

#

just don't do pacman -Sy like they did

#

it's always pacman -S or pacman -Syu

#

those are rookie mistakes lol

modern cradle
#

well i shouldn't update at all

#

it ll grab the laptop hardware drivers

#

xD

#

<.<

pulsar lark
#

he also uses systemd-boot

modern cradle
#

yeah

#

rip

#

meh

#

seems like u can't with grub

#

im just done

#

last solution install with mbr legacy

#

and hope

#

for the best

#

lol

pulsar lark
#

no just telling so you don't use the same commands

modern cradle
#

can't i just convert

#

uefi to legacy

pulsar lark
#

it's just changing the commands to grub paths

#

that's all

modern cradle
#

gpt to mbr

#

do you just convert it from gpt to mbr

#

or u have to also convert uefi to legacy

#

lol

pulsar lark
#

both actually lol

modern cradle
#

just reinstall i got it

pulsar lark
#

may I ask why the install-here-and-move-the-drive-there scenario?

modern cradle
#

?

#

nothing

#

was just testing

pulsar lark
#

ah

modern cradle
#

archinstall seems to do removable in automatic

pulsar lark
#

didn't know that actually

modern cradle
#

archinstall supports legacy bios?

#

i guess u just set the partitions manually

pulsar lark
#

yes, it's in the wiki

modern cradle
#

i mean

#

the automated install

pulsar lark
#

That I have no clue, now you're triggering my PTSD lol

#

hold on

modern cradle
#

ahhahaha

#

i ll let u know soon if it works or not

pulsar lark
#

the answer might be no

#

it checks the architecture you're on

modern cradle
#

so if i boot the usb in legacy mode

#

it ll install in legacy

pulsar lark
#

I'm not sure if you tell it you're on legacy since the CPU will be like he's lying

#

my google-fu says as long as legacy boot is on it should work but I don't trust it

modern cradle
#

ll see

pulsar lark
#

relevant?

modern cradle
#

rufus doesn't want to make it mbr

#

xd

pulsar lark
#

how big is your drive?

#

that also matters btw

modern cradle
#

16

#

arch is 1gb

#

lol

pulsar lark
#

no, sorry lol, I mean HDD

modern cradle
#

500gb

pulsar lark
#

oh that's fine

modern cradle
#

actually no

#

i think more

#

only my linux is gonna be 500

#

lol

#

should be a 1tb

#

so 900ish gb

pulsar lark
#

that's still fine

#

you're making me feel old by recalling that BIOS had a limit

modern cradle
#

i have my windows 10 server installed on dual boot

pulsar lark
#

till UEFI our lord and not savior showed up

modern cradle
#

but

#

i want to install arch

#

and convert my current win10

#

into vm

#

and run it from arch

#

with qemu or kvm

pulsar lark
#

and use looking glass?

modern cradle
#

what is that lol

pulsar lark
#

checkout looking glass

#

it's really nice but even with my modern system that was not working out

#

I went back to dual boot

modern cradle
#

nahhh

#

i dont want gpu passthrough and this stuff

#

its just a server

#

i could give a gpu

#

but nah

#

i have 2 gpu on my main pc

#

hahaha

#

both bad but good for now

#

an rx570 and a 1050 ti

pulsar lark
#

I take a TI over an AMD card in that era

#

though nvidia doesn't play nicely with linux

modern cradle
#

what

#

no

#

its ok

#

i used to do 1 gpu passthrough with this 1050 ti

#

wtf

#

why its showing rootfs

#

instead of the classic root@archiso

pulsar lark
#

on the prompt?

modern cradle
#

yea

#

after booting to usb

#

sh can't access tty

#

dafuq

pulsar lark
#

@modern cradle sorry went afk

#

fix it?

modern cradle
#

hmm

#

in what mode do i install the bios boot

#

i mean

#

format

#

ext4

#

or fat

pulsar lark
#

I don't recall BIOS being able to see filesystems

#

ext3 is a filesystem that is still around

modern cradle
#

Then format the boot partition into vfat: mkfs.vfat /dev/sda2.

Finally, set the root partition into ext4: mkfs.ext4 /dev/sda3

#

Also for bios

#

Just GRUB installation is different

pulsar lark
#

yep

modern cradle
#

Just copy and paste these commands to install the bootloader.

mkinitcpio -p linux pacman -S grub grub-install /dev/sda grub-mkconfig -o /boot/grub/grub.cfg

(please note that if you're installing this on uefi you should use these instead:

mkinitpio -p linux pacman -S efibootmgr grub grub-install --target=x86_64-efi --efi-directory=/boot/efi /dev/sda grub-mkconfig -o /boot/grub/grub.cfg
