[SOLVED] could someone help with setting up arch for triple boot?

[finite comet]

currently running a laptop with ubuntu and windows installed, and im not sure how exactly im supposed to install arch on top of all that. is there any specific steps i have to take or can i just follow the wiki?

[coral palm]

@finite comet make a partition for arch first

[small ridge]

When you say “on top of” what do you mean? Three separate bootable systems?

[finite comet]

yeah

[finite comet]

have to chkdsk first but im currently doing that

for some reason it says the volume ive selected to shrink may be corrupted so im tryna fix it 😭

alr i have 100 gb partition available now

what do i do from here? @coral palm

[wheat beacon]

Now you need to create an Ext4 partition in the empty 100g

[finite comet]

so i need to boot into the arch usb?

[wheat beacon]

mm yes now its good time

just follow the wiki, except for the bootloader part

[finite comet]

i only need to partition my arch root folder right?

[wheat beacon]

yes it will be enough

beginners dont need anything fancier than that 😛

regarding bootloader:
When turning on your pc, do you choose between windows and ubuntu in GRUB or in CMOS menu?

Im asking because you can either use one GRUB for the 3 oses,
Or you can install 2 Grubs, on Ubuntu and on Arch

[finite comet]

grub

planning to use grub for all 3

[wheat beacon]

ok, so keep in mind that you will have to run grub-mkconfig -o /boot/grub/grub.cfg
on ubuntu also, to make it aware of the new arch

and if you want to boot into Arch's grub, you will have to use the CMOS (BIOS/EFI) menu (e.g. F10 on boot?)

[finite comet]

any reason why i would wanna boot into archs grub specifically?

[wheat beacon]

Otherwise you will just see ubuntu grub by default 🙂

[wheat beacon]

Because you said youd like to install grub on all partitions?

or did you mean grub on Ubuntu only?

[finite comet]

i want one grub to manage every partition

[wheat beacon]

ok, so dont install grub on arch,
Instead use ubuntu's

[finite comet]

also this is my cfdisk rn, i just need to mkfs.ext4 the partition ive highlighted?

[wheat beacon]

yes

you can continue via the wiki from here, nothing special pretty much

[finite comet]

do i have to mount every partition?

or just the arch root one

[wheat beacon]

just arch root

and swap if you have

(with swapon)

[finite comet]

i dont have swap

[wheat beacon]

and EFI

partition

usually mounts into /boot/efi

[finite comet]

im not sure which one is the efi partition

can i check with cfdisk

oh yeah it says nvm

[wheat beacon]

the first one usually, should be FAT32, and under 1GB

[finite comet]

looks good i believe?

[wheat beacon]

yep!

doing really good so far!

[finite comet]

running pacstrap rn

[wheat beacon]

dont forget network tools (networkmanager?)

[finite comet]

yep i added that

should i make my fstab now or later?

[wheat beacon]

you can do it now

[finite comet]

wowies

[wheat beacon]

nice!!

chrooted? or booted?

[finite comet]

chroot

[wheat beacon]

right, uptime ratted you out

[finite comet]

uhhh ln -sf /usr/share/zoneinfo/ isnt doing anything

oh i just didnt type the full command

[wheat beacon]

lol, it happens

btw

[finite comet]

so this is the part where id usually install grub and stuff

so im not really sure what to do?

i setup language, hostname, user and stuff

[wheat beacon]

you need to run mkinitcpio -P to regenerate the kernel

and install intel-ucode normally

but you dont have to install grub

instead we will delegate it to ubuntu's grub,

[finite comet]

and how do we do that

[wheat beacon]

boot into ubuntu after that and run

[wheat beacon]

uuh

lol i just wrote the command

[finite comet]

so after im done with mkinitcpio -P i just reboot into ubuntu and run the grub-mkconfig command?

[wheat beacon]

did you follow the wiki fully?

[finite comet]

yes

[wheat beacon]

but skipped bootloader installation

[finite comet]

bootloader is the last step

[wheat beacon]

right

just run ls -l /boot

and verify that vmlinuz
and initram both exist

[finite comet]

i see vmlinuz-linux and initramfs-linux.img

[wheat beacon]

cool

reboot into ubuntu and update grub config

[finite comet]

alright

[wheat beacon]

^

[finite comet]

i exit'ed and reboot

[wheat beacon]

yep

when you run grub-mkconfig on ubuntu it should tell you that it has identified Arch's kernel

[finite comet]

for some reason my pc rebooted on windows 😭

give me a min

[wheat beacon]

ok

[finite comet]

found arch linux on /dev/nvme0n1p6

[wheat beacon]

nice!!

try rebooting now and you should see arch in grub 🙂

[finite comet]

let's see

yep its definitely there

[wheat beacon]

send your neofetch once you ready

[finite comet]

my keyboard is the wrong language again

should i change it in /etc/vconsole.conf or use localectl

[wheat beacon]

mmm i dont remember exactly, i think keyboard input lang is controlled by something else

verify localectl first

[finite comet]

found this on the wiki so ill do that

[wheat beacon]

so localectl it is

[finite comet]

yep
