archinstall disk partitioning problem

[golden dock]

Hello. I just set up Boot Camp on my Macbook Pro 2010 to have different partitions, both 250Gb on one drive. I planned to use arch linux on one of the partitions while still having MacOS on the existing other partition. In archinstall (live usb), I tried to configure the disk to only install arch on one partition of the disk. Theres a problem. When I tried to install, it gave me this error:

Invalid configuration: Boot partition not found

I thought that was no problem and assigned the mountpoint to be /mnt/boot. I tried to install again and it threw me another error but with the word Root instead of Boot:

Invalid configuration: Root partition not found

How can I fix this? I want to get past this screen and be able to dualboot Arch with MacOS.

quit out and lsblk please

[undone creek]

lsblk -f

[golden dock]

i want to install to sda3

[undone creek]

sda2 seems to be your root partition

are sda3 and sda1 boot partitions?

[undone creek]

fdisk -l

[golden dock]

sda3 is my bootcamp

sda1 is the boot partition

and sda2 is mac os x

[undone creek]

you're using ntfs?

for sda3?

[golden dock]

thats how macosx partitioned it

[undone creek]

what?

[golden dock]

in archinstall> Disk Configuration im able to manually partition that one ntfs partition and change it to ext4

[undone creek]

sda3 is macos's boot partition

why are you trying to put linux on it

[golden dock]

no

it says on sda3 and sda2 what types of partitions they are

apfs encrypted is what my osx partition is

[undone creek]

oh nvm (i dont know anything about macos), you'll need to create another partition for linux's boot partition

archinstall is probably getting confused with ur cursed setup, i'd recommend going through the install process manually

[undone creek]

go into cfdisk and manually partition

[golden dock]

ok

[undone creek]

create another boot partition for linux

make sure not to wipe anything macos related sda2 and sda1

and make sure to assign types

fdisk -l after

[golden dock]

is this good

im quite a newbie to arch so let me know if i did it wrong

[undone creek]

no

size sda4 down to 1g

and assign the efi type to it

[golden dock]

ok

i did that but theres an unpartitioned space that i cant resize sda3 with

[undone creek]

delete it

and then make a new one

[golden dock]

bro theres 2 free spaces now

[undone creek]

make a new one

[undone creek]

press enter on one of the free spaces

and then give it the rest of the space by just pressing enter

and then assign it teh linux root x86_64 type

[golden dock]

the maximum size from the free space is still separated

[undone creek]

shift+w type yes, press enter, press q to quit and then go back into it

execute cfdisk again

then

add the partition

with the type above

[golden dock]

yea i cant use all the free space

[undone creek]

[golden dock]

i can only use the space that was used by one of the partitions

[undone creek]

did you write ur changes quit out and then go back in?

[golden dock]

yes

[undone creek]

picture please

[golden dock]

i tried using the other space too but that gives the same answer

[undone creek]

try pressing n instead of pressing enter on the free space

[golden dock]

[undone creek]

try using fdisk instead
