[fervent pumice]

are you typing 'y' or 'yes' at the end?

[void prairie]

i type yes

let me send image

[fervent pumice]

sure, or try with fdisk instead if you prefer

[fervent pumice]

make sure you type it in the right case as well, I cant remember what it needs, yes, YES, Yes etc.

[devout flame]

@void prairie is this for installing arch?

[void prairie]

yes

[devout flame]

@void prairie btrfs or ext4?

[void prairie]

i have not formatted yet

[devout flame]

what are you going to format it as? @void prairie

[void prairie]

i want to format 3 partitions, a 100MB one as ext4 for the boot partition, one 4GB one as swap space and one for the rest storage normal space

[devout flame]

ok

[fervent pumice]

are you in the iso?

[void prairie]

yes in the install envinronment

[fervent pumice]

can you try just deleting the partitions?

I know on fdisk it's just:
fdisk /dev/sda
d
1
etc.

ah I see on cfdisk it's just go over to the left

[void prairie]

yes i delete all the partitions, write, then make the partitions again and write, then quit, then lsblk

[fervent pumice]

yeah delete them, and then write, and then quit, then lsblk

[void prairie]

yeah i did that

[fervent pumice]

try with fdisk, see what happens

[void prairie]

ok wait

[void prairie]

ok i do not know how to use fdisk

it is too hard for me

is fdisk absolutely necessary since i think cfdisk does the exact same thing fdisk does

[fervent pumice]

I just want to see if this is user error, and I'm not familiar with cfdisk

[void prairie]

cfdisk is just tui version of fdisk

[fervent pumice]

it's literally just:
fdisk /dev/<device>
and then:
d
1
enter
d
2
enter
d
3
enter
etc.
and when you're done, do:
w
enter

and that will delete and write the deletions of the partitions

remember to do the device, not the partitoin

e.g. /dev/sda NOT /dev/sda<number>

[void prairie]

ok

im on it

ok i did that, it failed to delete partition 2 and 3

'no such device or address'

so there is only dev/sda1

[fervent pumice]

to be clear you did:
fdisk /dev/sda
you didn't do:
fdisk /dev/sda1
right?

[void prairie]

yes i did the upper one

fdisk /dev/sda

[fervent pumice]

can you share mount -v |grep sda

oh me derp is typing, so probably a solution about to drop that I don't know about lol

[white pumice]

You could also try running wipefs -a /dev/sda to delete the partition table for the drive

[fervent pumice]

as far as I know a partition being lvm shouldn't effect deleting the partition, right?

[white pumice]

I don't think so?

[void prairie]

nothing happens

[void prairie]

do i do this?

[fervent pumice]

if the wipfs command doesn't work, mount all 3 partitions, and then repeat that command

[void prairie]

ok

i will wipefs

[fervent pumice]

if that doesn't work I want to see if those partitions when mounted show that they are rw, or just r, or neither, because if they aren't w then that might be related

[void prairie]

ok it does not work: device or resource busy

[fervent pumice]

only other things I can suggest are rebooting, in case there's an error with the iso, checking the iso hash is actually correct, seeing if your bios can wipe a disk, and seeing if your bios has a relevant setting preventing the device from being written to.

I'm a little sus that your device may be damaged.

[void prairie]

i will reboot

[fervent pumice]

@white pumice type your message even if it contradicts me, because you're usually someone who teaches me things (whether you mean to or not)

[white pumice]

I was just saying the same thing

[void prairie]

ok i rebooted and here is the result:

loop0
sda
sdb-|
| -sdb1
| -sdb2

[fervent pumice]

hmmm, that's interesting

so it looks like sda has been wiped of it's partitions as you wanted

are you using ventoy out of interest? I'm assuming sdb is ventoy

[void prairie]

no im using rufus

[fervent pumice]

huh, didn't know that used 2 partitions

rufus can be a bit tempremental, but anyway, can you write to sda now?

[void prairie]

also sda is the main hard disk

i will see if i can

hold on

okay now i have:

loop0
sda
| - sda1
| - sda2
| - sda3
sdb
| - sdb1
| - sdb2

[white pumice]

so it worked?

[void prairie]

and all the sda block devices are as big as i wanted them to be

yes it worked

reboot did it

[white pumice]

That's good to hear

[void prairie]

very much thank you @fervent pumice and me derp

Thank you

[fervent pumice]

@void prairie can you mark as solved? 🙂

unless there's anything further?

[void prairie]

oh ok

[fervent pumice]

I mean, unless there is a further issue?
